This Saturday at UFC 137 in Las Vegas served up a first-rate bout of MMA between Nick Diaz and former champion BJ Penn. The fight, lively from start to finish and won by Diaz, rightfully earned the two warriors the 75,000-dollar fight of the night bonus.
Submission of the night honors went to Donald Cerrone for the rear-naked choke that earned him his sixth win in a row. Now the best knockout prize went to Bart Palaszewski for dropping Tyson Griffin in the first round.
