well the commisioners of the tour thought it was 2 major infringements and they have kicked Renshaw out of the Tour, I didn't see anything wrong with the headbutts it looked like the other rider was infringing into his space but when renshaw sat up he did cross into the line of Farrar and forced him into the barriers
I think they should have just relegated him to last place today and fined him, not kick him off the tour completely
