Its funny. Even if the undercard guys in the UFC did something like that there would be an UPROAR! that guys career would have a black mark forever. In Boxing the Main Event guy and arguably biggest name in boxing (Not even so much arguably, more fact) can pull something like that and really no one cares that much. Mayweather haters call him a bitch and Mayweather lovers say the fight was restarted so he did nothing wrong. Even if that is the case what ever happened to honor in combat sports??? especially since Ortiz was in the middle of apologizing for the headbutt lmao. Who the **** does that...
