Sean Sherk is the retired former UFC lightweight champion and a former challenger for the UFC welterweight title.
He most recently faced Evan Dunham, handing the prospect his first loss via a controversial split decision. Many thought Dunham deserved the win due to his late success in the third round, but they forgot the fact that Sherk had won the first two rounds. They ignored the fact that he thus deserved the 29-28 decision victory...
Nearly three years after the Dunham fight Sherk officially retired from mixed martial arts on September 2nd, 2013.
