Mayweather got headbutted by a frustrated Ortiz who was clearly losing the fight. Ref says fight, Mayweather fights. "Protect yourself at all times", its said in EVERY SINGLE FIGHT. Yes, hitting someone while they are trying to tip-touch with you is not that nice, but anyone who has ever been involved in boxing will agree with me that what Ortiz did was borderline retarded, by exposing himself like that after blatantly trying to damage the dude with a headbutt.
And just to get it straight, I hate Mayweather, as a boxer he is fucking amazing, but his loud ass won't be shit in my eyes til' he mans up and gets in there with Pacquiao.
