Object of the game

 

The object of the game is to score points by advancing the ball to the opponent's end zone for a touchdown, which is worth six points. A team may also score by kicking the ball through goal posts in the back of each end zone for a field goal, which is worth three points. It is also possible for a team to score points by tackling the other team's ball carrier in their own end zone, called a safety, which is worth two points. Additionally, after scoring a touchdown, a team may attempt a close-range field goal kick to add an extra point, bringing the total points to seven, or the team may attempt to advance into the end zone to add two extra points, called a two-point conversion, bringing the total points to eight. The team with the most points when time has expired wins.

[edit] Time of play

 

Collegiate and professional football games are 60 minutes long, divided into four quarters of 15 minutes each. In high school football, 12 minute quarters are usually played. The clock is stopped frequently, however, so that a typical college or professional game can exceed three hours in duration. The referee controls the game clock and stops the clock after any incomplete pass or any play that ends out of bounds. In addition, each team is allowed 3 timeouts in each half that they may use at their own discretion.

 

The clock may also be stopped for an officials' time-out, after which, if the clock was running, it is restarted. For example: if there is a question as to whether or not a team has moved the ball far enough for a first down, the officials may bring the chains in to measure. While this measurement is taking place, the officials will signal for a stoppage of the clock. Once the measurement is finished and the ball is spotted, the referee will then signal for the clock to restart. Additional situations where officials may take a time-out are to administer a penalty or for an injured player to be removed from the field.

 

In addition to the game clock, a separate play clock is also used. This counts down the time the offense has to start the next play before it is assessed a penalty for delay of game (see below). This clock is typically 25 seconds from when the referee marks the ball ready for play. The NFL and NCAA use a 40-second play clock that starts immediately after the previous play ends, though for certain delays, such as penalty enforcement, the offense has 25 seconds from when the ball is marked ready. The purpose of the play clock is to ensure that the game progresses at a consistent pace, preventing unnecessary delays.

 

Officials also call for media time-outs, which allow time for television and radio advertising. They also stop the clock after a change of possession of the ball from one team to the other. Successful PATs (Point(s) After Touchdown), a field goal try, or a kickoff may also warrant stopping the clock. If an instant replay challenge is called during the game, the referees signal for a media time out. The referee signals these media time-outs by first using the time out signal, then extending both arms in a horizontal position.

 

Separating the first and second halves is halftime. Teams change ends of the field at the end of the first quarter and the end of the third quarter. In the NFL, an automatic timeout is called by the officials when there are two minutes left in both the second and the fourth quarters; this is most commonly referred to as the two-minute warning. No such warning is normally given in amateur football, though if there is no visible stadium clock, the referee will give a two-minute warning (four minutes in high school).

[edit] Overtime

 

If a game is tied at the end of four quarters, overtime is played.

 

* In the NFL, overtime periods are 15 minutes in length and are sudden death, meaning that the team that scores first, by any means, wins, and the game automatically ends (referred to in recent years as a walk-off touchdown, walk-off field goal or in rare situations, a walk-off safety). A coin flip is employed to determine which team will gain possession first; the winning team has the option to either receive the kickoff or choose the side of the field they wish to defend. During the regular season in the NFL, one overtime period is played (with each team receiving two time outs), and if neither team scores during overtime, the game officially ends in a tie. In the playoffs, as many overtimes are played as are necessary to determine a winner. Ties are rare in the NFL; the game between Philadelphia and Cincinnati on November 16, 2008 ended in a tie, the first tie since 2002[1]. Philadelphia quarterback Donovan McNabb later stated that he didn't know games could end in a tie.[2]

 

* NFL Europa, a defunct league run by the NFL, used a 10-minute overtime period, with the constraint that each team must have the opportunity of possession; once both teams have had such an opportunity, the overtime proceeds in a manner similar to the NFL's. Thus, if Team A has the first possession of overtime and scores a touchdown and converts their kick (thus being 7 points ahead of Team B), Team A would then kick off to Team B (In the NFL, the game would have ended with the touchdown, without a conversion being attempted). Team B would have to match or exceed the 7 point difference within this ensuing possession; exceeding it would end the game immediately, while matching the difference would result in a kickoff to Team A. From this point, the overtime is sudden death. The Arena Football League, since 2007, and the United Football League both use this rule.

 

* The Arena Football League, the principal indoor football league in the U.S., and its official minor league af2 use a 15-minute overtime period that otherwise operates under the NFL Europa rules (with each team getting one opportunity of possession).

 

* The defunct World Football League, in its first season of 1974, used an overtime system more analogous to the system long used in international soccer. The overtime consisted of one 15-minute period, which was played in its entirety and divided into two halves of 7½ minutes each, with each half starting with a kickoff by one of the teams. The league changed to the NFL's sudden-death format for its second and last season in 1975.

 

* In college and high school football, an overtime procedure (the Kansas plan) ensures that each team has equal opportunity to score. In college, both teams are granted possession of the ball at their opponents' 25 yard-line in succession. A coin flip takes place, with the winning team having the option either 1) to declare that they will take the ball first or second, or 2) to decide on which end of the field the series will occur (both teams' series occur on the same end of the field). The losing team will have the first option in any subsequent even-numbered overtime. In the first overtime, the team with first series attempts to score either a touchdown or a field goal; their possession ends when either a touchdown or a field goal have been scored, they turn the ball over via a fumble or an interception, or they fail to gain a first down. After a touchdown, a team may attempt either an extra-point or a two-point conversion. However, if the team on defense during the first series recovers a fumble and returns it for a touchdown, or returns an interception for a touchdown, the defensive team wins the game. (This is the only way for a college overtime game to end without both teams having possession.) Otherwise, regardless of the outcome of the first team's series (be it touchdown, field goal, or turnover), the other team begins their series. If the score remains tied after both teams have completed a series, a second overtime begins. If the score remains tied after two overtimes, teams scoring touchdowns are required to attempt a two-point conversion from the third overtime on. Just as in regulation, if a defensive team recovers a fumble/returns an interception to the end zone during a two-point conversion attempt, they will receive two points.

 

* In high school football, in most of the states, each team is granted possession of the ball at the 10-yard line, meaning that a team cannot make a first down without scoring except via a defensive penalty that carries an automatic first down (such as defensive pass interference or roughing the passer). As is the case with the college overtime rule, the team that wins the coin toss will have the choice as to whether to take the ball first or second, or decide at which end of the field the overtime will be played. The other major difference between overtime in college football and high school football is that in high school football, if the defense forces a turnover, they may not score. However, in Texas, the college overtime rule is used, as both the University Interscholastic League, which governs interscholastic activities for Texas public high schools, and the Texas Association of Private and Parochial Schools, the largest analogous body for Texas private high schools, play by NCAA football rules with a few modifications for the high school level.

 

* The defunct XFL used a modified Kansas Plan which, upon the first team scoring, required the opponent to score the same or greater amount of points in the same or fewer downs (i.e. if the first team scored a touchdown, and converted the one-point conversion in three downs, the opponent would have to match that touchdown and conversion in three downs as well, and would not get a fresh set of four downs). Each team started at the 20-yard line, but like high school, there were no opportunities for first downs. The league also banned field goals except for on a fourth down.

 

[edit] Playing the game

[edit] Coin toss

 

The game begins with a kickoff, which is one type of free kick (see below). Prior to the game, captains from each team participate in a coin toss. The winner of the toss may make one of the following choices—to kick off, to receive and have the other team kick off, or to choose an end of the field to defend—or they may defer and have first choice to start the second half and give the other team first choice in the first half. If the team with first choice chooses to receive the football (which they do in most cases so they can go first on offense), then the other team will decide which end they want to play on.

 

The option to defer the choice has existed in amateur football for several years. Prior to 2008, the NFL required the winner of the toss to exercise its option in the first half, but a rules change allows the team winning the toss to defer starting with the 2008 season.[3] Thus the winner of the toss may now choose to go first on offense for the start of the first or second half.

 

A kickoff is also used to start the second half of the game. The team that did not have first choice of options to start the game gets first choice to start the second half.

 

Kickoffs also take place after each try for extra point and field goal, with the scoring team kicking off.

[edit] Downed player

 

A player carrying the ball (the runner) is downed when any of the following occurs:

 

* Any part of the runner other than his hands or feet touches the ground. This may be as a result of:

o Contact by an opponent (called down by contact) where the opponent tackles the runner by pushing him, grasping him and pulling him to the ground, sliding into his legs, or touching him in any manner prior to any part of the runner other than his hands or feet touching the ground. Unlike the use of the word tackle in other sports, if the opposing player fails to down the ballcarrier, it is merely an attempted tackle.

o Accidentally touching the ground, such as by slipping or falling without having been touched by an opponent. However, in professional football, the runner is not considered down in this situation, but may rise and continue to run until he is down by contact, as defined above.

o Intentionally downing the ball: intentionally kneeling, verbally declaring "I'm down" (except in college), or similar actions. For example, to protect himself from violent hits by opponents attempting to tackle him, the quarterback may choose to slide to the ground feet-first. This slide is interpreted as intentionally downing the ball, and opponents may then be penalized for hitting him.

* The runner goes out of bounds: that is, any part of his body (including his hands or feet) touches the ground, or anything other than another player or an official, on or past a sideline or an endline. Note that the sideline itself is out of bounds, so that the runner is deemed out of bounds if he steps on or touches any part of it. Note also that a runner may carry the ball in such a manner that it is over the sideline, so long as the ball or runner does not touch anything out of bounds.

* The runner's forward progress toward the opponents' goal line is stopped by contact with an opponent, with little chance to be resumed. The exact moment at which the player's forward progress stops is subject to the judgment of the officials. In particular, for the protection of the quarterback, he is considered down as soon as an official judges that he is in the grasp of an opponent behind the line of scrimmage, and the tackling defensive player(s) will be awarded with a sack. If he is driven backward by the opponent, the ball will be spotted where his forward progress was stopped.

 

[edit] Scrimmage downs

 

The majority of a football game takes place on plays, or downs, that begin at the line of scrimmage. The officials spot the ball (place it in a designated spot on the field) on the line of scrimmage and declare it ready for play.

[edit] Positions

Main article: American football positions

 

The width of the spotted football defines the width of the neutral zone, an area of the field no player other than the snapper may position themselves in or above before the snap. Each team has its own line of scrimmage which is a vertical plane from sideline to sideline that passes through the point of the ball nearest its own goal line.

 

The players on offense must arrange themselves in a formation, all behind their line of scrimmage (that is, on the side of the line nearest their own end zone). At least seven players on offense must position themselves "on" (very near) the line; up to four may be farther from it. All players on offense must come set, or stop moving, before the snap. Once set, the offense may "shift" and come set again, as long as they do not simulate the beginning of a play. Additionally, one player at a time, called the man in motion, may be in motion, so long as he is not moving forward (toward the opponents' goal line) at the time of the snap.

A formation at the line of scrimmage. Offensive players are marked by O symbols, defensive players by X symbols. There are many, many variations of football formations.

 

Offensive linemen are players who line up on the line of scrimmage. The center normally lines up directly over the ball. On each side of him is an offensive guard and on both sides next to these guards are the offensive tackles. Rules require that 5 offensive linemen wear jerseys numbered 50–79. Usually the 5 interior linemen are the ones who wear these numbers. The rules prohibit the 5 interior linemen from being eligible receivers for forward passes. The offense must position 7 players on the line. In order to be an eligible receiver, a linemen must be at either end of the lines, sometimes called tight ends, or split ends. The eighth, ninth and tenth players, who are eligible receivers, can be positioned in the backfield and would then be called running backs, or they can be positioned directly behind the line of scrimmage (to avoid being positioned as one of the seven required linemen.) The offensive players are called backs if they are positioned in the backfield (the area behind the linemen), or wide receivers if they are positioned close to the sideline. A wide receiver on the line is called a split end. The eleventh offensive player is usually called the quarterback and is an eligible receiver. Usually this player is in position to receive the ball from the center; running backs position themselves in a position planned by the play that has been called in preparation for the play; and wide receivers line up in the backfield positioned to go downfield to catch passes or block. Included as running backs, a halfback or a tailback will often be in position to run with the ball; a fullback will be in position to block or sometimes run with the ball.

 

The players on defense may arrange themselves in any manner, as long as all players are "behind the line" (that is, on the side of the line nearest their own end zone). Players who line up opposite the offensive line are called defensive linemen, usually with one or two defensive tackles in the middle (although, a single defensive tackle is often called the nose guard) and with one defensive end on each side. Behind and adjacent to the linemen are the linebackers; positioned opposite the wide receivers are the cornerbacks. Two other defensive players, called safeties position themselves somewhat freely, but usually in the middle of the field behind the linebackers. These last 4 players are often referred to as the secondary.

[edit] Starting the down

 

A scrimmage down begins with a snap, where the center throws or hands the ball backward to one of the backs, usually the quarterback. The down ends when the ball becomes dead (see below). The ball is typically next spotted where the ball became dead; however, if it became dead outside the hash marks, it is brought in on the same yard line to the nearest hash mark. This spot becomes the line of scrimmage for the next play. In the case of an incomplete forward pass, the ball is returned to the spot where it was snapped to begin the previous play. A fumbled ball that goes out of bounds is declared dead and possession remains with the team that most recently had control of the ball.

[edit] Dead ball

Main article: Dead ball (American football)

 

The ball becomes dead, and the down ends, when:

 

* the ballcarrier is downed, as described above;

* a forward pass falls incomplete (it touches the ground before possession is secured by a player);

* the ball or ballcarrier touches the sideline or endline or otherwise goes outside the field of play ("out of bounds");

* the ballcarrier or the ball, except on a scoring field goal attempt, hits any part of the goalpost (even if it bounces back onto the field);

* a team scores;

* a kick receiver makes a fair catch (waving his arm above his head to signal a fair catch, where the kicking team is not allowed to interfere with him or hit him after the catch, but in return he is not allowed to run), or a member of the receiving team gains possession after a fair catch signal was given;

* a member of the kicking team possesses a kicked ball (e.g. "downing" a punt allowed to roll by the receiving team by holding it to stop its roll);

* a kicked ball comes to rest;

* a touchback occurs; or

* under NFL or college rules, on fourth down (or, in the NFL, on any down after the two-minute warning in either half), a ball fumbled forward by the offensive team is recovered by an offensive team player other than the fumbler.

 

The nearest official typically blows his whistle after the ball becomes dead to alert the players that the down has already ended. If the ball is alive and the official sounds an inadvertent whistle, then the ball still becomes dead, but the team in possession of the ball may elect to have the down replayed or take the spot where the ball was declared dead. If the ball was loose from a fumble, then the ball can be put into play at the spot of the fumble. If the ball was in flight from a kick or a pass, then the down is always replayed.

[edit] Free kick downs

 

A free kick is a down which does not occur from scrimmage. The kicking team begins behind the ball, while the receiving team must remain at least 10 yards downfield before the ball is kicked.

[edit] Kickoffs

 

A kickoff is a type of free kick where the ball is placed on a tee (or held) at the kicking team's 30-yard line (40 for high school). The kicking team's players may not cross this line until the ball is kicked; members of the non-kicking (or "receiving") team are similarly restrained behind a line 10 yards further downfield (the 40-yard line, or 50 for high school). A valid kickoff must travel at least this 10-yard distance to the receiving team's restraining line, after which any player of either team may catch or pick up the ball and try to advance it before being downed (see "Downed player," below). In most cases, the ball is kicked as far as possible (typically 40 to 70 yards), after which a player of the receiving team is usually able to secure possession (since the members of the kicking team cannot start downfield until after the ball is kicked). Occasionally, for tactical reasons, the kicking team may instead choose to attempt an onside kick, in which the kicker tries to kick the ball along the ground just over the required 10-yard distance in such a manner that one of his own teammates can recover the ball for the kicking side.

[edit] Receiving a kickoff

 

A member of the receiving team gaining possession of the ball on a kickoff may attempt to advance it as far as he can toward the kicking team's goal line before being downed. Once the ball carrier is downed, the play is whistled dead and the ball is placed by the officials at the point where the play ended; this spot then becomes the line of scrimmage for the ensuing play. A kick that travels through or goes out of bounds within the end zone without being touched, or is caught by the receiving team in the end zone but not advanced out of it, results in a touchback; the ball is then placed at the receiving team's 20-yard line, which becomes the line of scrimmage.

 

A kickoff that goes out of bounds anywhere other than the end zone before being touched by the receiving team is an illegal kick: the receiving team has the option of having the ball re-kicked from five yards closer to the kicking team's goal line, or they may choose to take possession of the ball at the point where it went out of bounds or 30 yards from the point of the kick (25 yards in high school), whichever is more advantageous.

[edit] Other free kicks

 

A free kick is also used to restart the game following a safety. The team that was trapped in its own end zone, therefore conceding two points to the other team, kicks the ball from its own 20-yard line. This can be a place kick (in the NFL, a tee cannot be used), drop kick or punt.

 

In the NFL and high school, a free kick may be taken on the play immediately after a fair catch; see "fair catch kick" below.

[edit] Scoring

[edit] Field goal (3 points)

 

A field goal is scored when the ball is place kicked, drop kicked, or free kicked after a fair catch or awarded fair catch (High School or NFL only) between the goal posts behind the opponent's end zone. The most common type of kick used is the place kick. For a place kick, the ball must first be snapped to a placeholder, who holds the ball upright on the ground with his fingertip so that it may be kicked. Three points are scored if the ball crosses between the two upright posts and above the crossbar and remains over. If a field goal is missed, the ball is returned to the original line of scrimmage (in the NFL, to the spot of the kick; in high school, to the 20-yard line if the ball enters the end zone, or otherwise where the ball becomes dead after the kick) or to the 20-yard line if that is further from the goal line, and possession is given to the other team. If the ball does not go out of bounds, the other team may catch the kicked ball and attempt to advance it, but this is usually not advantageous. One official is positioned under each goalpost; if either one rules the field goal no good, then the field goal is unsuccessful. A successful field goal is signaled by an official extending both arms vertically above the head. A team that successfully kicks a field goal kicks off to the opposing team on the next play.

[edit] Touchdown (6 points)

 

A touchdown is achieved when a player has legal possession of the ball and the ball crosses an imaginary vertical plane above the opposing team's goal line. After a touchdown, the scoring team attempts a try (see below). A successful touchdown is signaled by an official extending both arms vertically above the head.

 

For statistical purposes, the player who advances the ball into or catches it in the end zone is credited with the touchdown. If a forward pass was thrown on the play, the passer is also credited with a passing touchdown.

[edit] Try for extra point (1 or 2 points)

 

A try is more frequently called an extra-point attempt or a PAT (abbreviation of "Point After Touchdown"[4]). Either one or two additional points may be scored during the try. The ball is spotted at the 2 yard line (NFL) or 3 yard line (college/high school), and the team is given one untimed play to earn points:

 

* The offensive team may attempt to kick the ball through the goalposts, in the same manner that a field goal is kicked. This option is almost always chosen, because a two point conversion attempt is much riskier. If successful the team is awarded one point, referred to as an extra point. Because the extra point is almost always successful (especially in NFL play), sportscasters will refer to a team up or trailing by seven (not six) points as being "up/trailing by a touchdown".

 

* The offensive team may attempt to advance the ball via run or pass into the end zone, much like a touchdown on the extra-point attempt, except that it receives two points. This is called a two-point conversion. The success rate for two-point conversions is less than 40 percent in the NFL and college, making the two-point conversion attempt a risky tactic; thus it is usually attempted only when two points will help the team but one point will not.

o For example, suppose that it is late in the game with a score of 21-10 and the losing team scores a touchdown, making the score 21-16. The scoring team will usually attempt the two-point conversion, because if successful, a three-point deficit later could be matched with one field goal; failure to convert would result in a five-point deficit that would not be surmounted without another touchdown—a situation no worse than the four-point deficit achieved with a kicked extra point.

o Another example would be if a team scores a late-game touchdown, and is instantly down by two points. A successful two-point conversion would tie the game, and likely force overtime. In very rare and risky instances, a trailing team who scored a touchdown, and is immediately down by 1 point, may attempt a two-point conversion to gamble on a win and avoid overtime.

 

* Under college rules, if the defensive team gains possession and advances the ball the length of the field into the opposite end zone on the try (for example by an interception or a fumble recovery, or by blocking a kick and legally recovering the ball), they score two points. This is officially recorded as a touchdown scored by the defense. The NCAA adopted this rule in 1990.

o This scenario cannot occur under NFL or high school football rules; the ball is ruled dead and the try is over immediately when the defense gains possession.

 

* In the extremely rare event that the offensive team scores a safety on the try, it receives one point. In college football, this can occur when, for example, the defense gains control of the ball and attempts to advance it, then fumbles it out of bounds in its own end zone. In the NFL, since the try ends once the defense gains possession, a safety can only be scored if a defensive player bats a loose (fumbled) ball out of bounds in the end zone.

 

* The game clock is not advanced during a try, however, the play clock is enforced. A delay of game penalty, false start, or similar penalty, by the offense results in a 5-yard penalty assessed for the try. Typically, penalties charged against the defense give the offensive two options: half the distance to the goal for the try, or assessing the full penalty on the ensuing kickoff. Since the try is not timed by the game clock, if a touchdown is scored as regulation time expires (and game clock subsequently reads :00), the try is still allowed to be conducted. This instance is relatively common as teams score a game-tying (or game-winning) extra point after regulation has expired.

o During sudden-death overtime, particularly in the NFL, if a team scores a touchdown in the overtime period, the game is immediately over, and the try is not attempted.

 

* The officials' signal for a successful try, whether an extra point or a two point conversion, is the same as for a touchdown. After the try, the team that scored the touchdown kicks off to the opposing team.

 

[edit] Safety (2 points)

Main article: Safety (football score)

 

The uncommon safety is scored if a player causes the ball to become dead in his own end zone; two points are awarded to the opposing (usually defending) team. This can happen if a player is either downed or goes out of bounds in the end zone while carrying the ball, or if he fumbles the ball, and it goes out of bounds in the end zone. A safety is also awarded to the defensive team if the offensive team commits a foul which is enforced in its own end zone. A safety is not awarded if a player intercepts a pass or receives a kick in his own end zone and is downed there. This situation, in which the opponent caused the ball to enter the end zone, is called a touchback; no points are scored, and the team that gained possession of the ball is awarded possession at its own 20 yard line. If the interception or reception occurs outside the end zone, and the player is carried into the end zone by momentum, the ball is placed at the spot of the catch and no safety is awarded. A safety is signaled by a referee holding both palms together above the head, fingertips pointing upwards. After a safety, the team that conceded the safety kicks a free kick (which may be a punt, place kick, or drop kick) from its 20 yard line.

[edit] Fair catch kick (High school or NFL only, 3 points)

Main article: Fair catch kick

 

A free kick (see below) may be taken on the play immediately after any fair catch of a punt. In the NFL, if the receiving team elects to attempt this and time expired during the punt, the half is extended with an untimed down. The ball must be held on the ground by a member of the kicking team or may be drop kicked; a tee may not be used. (High school kickers may use a tee.) This is both a field goal attempt and a free kick; if the ball is kicked between the goal posts, three points are scored for the kicking team. This is the only case where a free kick may score points. This method of scoring is extremely rare; it is only advantageous when a team catches a very short punt with very little time left. Note that a team is unlikely to be punting with only a few seconds left in a half, and it is rarer still for punts to be caught near field goal range. The officials' signal for a successful fair catch kick is the same as for a field goal.

[edit] Officials

Main article: Official (American football)

 

The game is officiated by a crew of three to seven officials. Every crew will consist of a referee, who is generally in charge of the game and watches action on the quarterback and in the offensive backfield; an umpire, who handles spotting the ball and watches action on the offensive line; and a head linesman, who supervises placement of the down box and line-to-gain chains. The crew may also consist of a line judge, back judge, field judge and side judge, in the order listed: i.e. a crew of five officials has a referee, umpire, head linesman, line judge and back judge.

 

Officials are selected by the teams in advance or appointed by the governing league. Note that unlike some other sports, no football officials—not even at the NFL level—are full-time employees of the league; they all officiate on a part-time basis.

 

During the game, the officials are assisted in the administration of the game by other persons, including: a clock operator to start and stop the game clock (and possibly also the play clock); a chain crew who hold the down indicator and the line-to-gain chains on the sideline; and ball boys, who provide footballs to officials between downs (e.g. a dry ball each down on a wet day). These individuals may be provided by the teams involved—it is not uncommon for a high school coach's son to act as ball boy for the team.

[edit] Fouls and their penalties

Main article: Penalty (American football)

 

Because football is a high-contact sport requiring a balance between offense and defense, many rules exist that regulate equality, safety, contact, and actions of players on each team. It is very difficult to always avoid violating these rules without giving up too much of an advantage. Thus, an elaborate system of fouls and penalties has been developed to "let the punishment fit the crime" and maintain a balance between following the rules and keeping a good flow of the game. Players are constantly looking for ways to find an advantage that stretches the limitations imposed by the rules. Also, the frequency and severity of fouls can make a large difference in the outcome of a game, so coaches are constantly looking for ways to minimize the number and severity of infractions committed by their players.

 

It is a common misconception that the term "penalty" is used to refer both to an infraction and the penal consequence of that infraction. A foul is a rule infraction for which a penalty is prescribed.[5] Some of the more common fouls are listed below. In most cases when a foul occurs, the offending team will be assessed a penalty of 5, 10 or 15 yards, depending on the foul. Also, in most cases, if the foul is committed while the ball is in play, the down will be replayed from the new position (for example, if the offense commits a foul on a first-down play, the next play will still be first down, but the offense may have to go 15 yards, or farther, to achieve another first down.) But if a defensive foul results in the ball advancing beyond the offense's first-down objective, the next play will be the first down of a new series. Some penalties (typically for more serious fouls), however, require a loss of down for the offense; and some defensive fouls may result in an automatic first down regardless of the ball position. In all cases (except for ejection of a player or, in rare cases, forfeiture of the game), the non-offending team is given the option of declining the penalty and letting the result of the play stand (although the Referee may exercise this option on their behalf when it is obvious), if they believe it to be more to their advantage. For some fouls by the defense, the penalty is applied in addition to the yardage gained on the play. Most personal fouls, which involve danger to another player, carry 15-yard penalties; in rare cases, they result in offending players being ejected from the game. In the NFL, if a defensive foul occurs after time has expired at the end of a half, the half will be continued for a single, untimed play from scrimmage. Under college rules, any accepted penalty when time has expired at the end of any quarter results in an extension for one untimed down.

 

In the NFL, with three exceptions, no penalty may move the ball more than half the distance toward the penalized team's goal line. These exceptions are defensive pass interference (see the discussion of that foul for more details), intentional grounding, and offensive holding – but in this last case the exception pertains only if the infraction occurs within the offensive team's own end zone, in which case an automatic safety is assessed (intentional grounding from the end zone also carries an automatic safety). Under college rules, the same half-the-distance principle applies, but any offensive fouls involving contact in their end zone (eg. holding, illegal blocking or personal fouls) result in a safety.

 

Note: The neutral zone is the space between the two free-kick lines during a free-kick down and between the two scrimmage lines during a scrimmage down. For a free-kick down, the neutral zone is 10 yards wide and for a scrimmage down it is as wide as the length of the football. It is established when the ball is marked ready for play. No player may legally be in the neutral zone except for the snapper on scrimmage downs, and no one except the kicker and the holder for free kick downs.

 

[edit] Timeouts

 

Each team receives three timeouts per half (if the game goes to overtime, each team receives additional timeouts), making for a total of six timeouts per team in a regulation game. Timeouts received in the first half may not be used in the second half or overtime. In professional football, a team must have at least one remaining timeout to challenge an official's call.

[edit] Instant replay

 

In the NFL, a number of rulings (but typically not fouls) can be reviewed by officials or challenged by coaches (see Instant replay). If a coach wants to challenge a play, he must do so before the next play begins, and he does so by throwing a red flag similar to the officials' yellow flags. Coaches are allowed two challenges per game and may be granted a third if their first two are successful. The team loses a timeout if they lose the challenge. Plays inside the two-minute-warning cannot be challenged; any review of that play must be initiated by a replay official off-field. The referee performs the actual review via a video screen on the sideline. The referee will announce the result of instant replay reviews over his wireless microphone.

 

In college, coaches are allowed one challenge per game by first requesting a timeout. Otherwise, a replay official in the press box observes all plays. If he deems a ruling may be in error, he notifies the officials on the field to interrupt the game before the beginning of the next play. The replay official performs the review and relays the decision to the referee, who announces the result. Not every conference employs replay, which is optional.

 

High school rules do not provide for video review of any decisions by officials during the game. Further, the use of television or video tape for coaching purposes during the game is prohibited. If a coach feels a rule has been misinterpreted, he may call timeout and request a coach-referee conference to discuss the ruling with the referee, but no replay equipment will be consulted during the conference.
