1. UFC 126
Victim: Vitor Belfort
Vitor Belfort stood no chance when he ran into Anderson Silva's lead foot. His face was crushed and he was KO'd as Silva was able to retain his middleweight championship in this bout. Belfort instantly hit the mat and Silva got in a few more shots before the ref stopped the match. Only The Spider could deliver a knockout that could potentially leave you with both a concussion and athlete's foot in your grill.
