Rashad Evans gave a vicious knee to Tito Ortiz in the chest and pummeled Ortiz's head to earn the TKO nearly 5 minutes into the 2nd round of UFC 133's main event Saturday night.

Evans had Ortiz pinned against the cage when he blasted a right knee into the chest that crumpled Ortiz and finished Ortiz with punishing right hands, and is now the No. 1 contender for the light heavyweight championship.

Evans and Ortiz fought four years earlier to a draw in 2007 and Ortiz took this fight on short notice after his victory in UFC 132 last month.
