Edgar amassed a 5–0 record before trying out for season five of The Ultimate Fighter. Edgar tried out in front of Ultimate Fighting Championship (UFC) president Dana White and matchmaker Joe Silva, but was not selected to be on the show. However, a month later the UFC contacted Edgar and asked if he would accept a fight with fellow undefeated fighter Tyson Griffin at UFC 67. Griffin caught Edgar in a deep kneebar at the end of the fight, but Edgar refused to tap and lasted out the remainder of the round to win by unanimous decision. The fight has been frequently rebroadcast on UFC Unleashed.
