Fan favorite Paul Felder, 37, announces retirement from MMA

Paul Felder, a fan favorite and staple of the UFC's lightweight rankings for years, announced his retirement from mixed martial arts on Saturday. Felder (17-6), of Philadelphia, broke the news during Saturday's broadcast of UFC Fight Night, on which he was serving as a commentator. The announcement was a little surprising as Felder, 37, is still considered one of the best lightweights in the world and headlined UFC events in his last two performances.
