The Worst Case Scenario Survival Manual insists that if you’re in a situation where the probability of you getting punched in the head is at 100%, you should lean your head forward and take the blow directly just above your forehead, on the top of our noggin. There’s a chance you can break the other person’s barefist and in return, you receive little to no damage. I’ve never practiced this method, due to he fact that I avoid any scenario which involves me getting punched directly in the head. However, if you are presented with an opportunity to headbutt another person’s head, just do it as hard as possible and chances are you will be the last man standing.
David Haye doesn’t have much to say about Victor Ortiz’s blatant headbutt from last weekend’s PPV fight against Floyd Mayweather, but he does have an opinion about UFC 135 and TUF in this AddictedMMA interview.
