UFC Hall of Famer and former lightweight champion Frankie Edgar is picking back up his gloves — but only metaphorically.

Edgar, 43, is expected to face fellow UFC veteran Jimmie Rivera at a Bare Knuckle Fighting Championships event Oct. 4 in his home state of New Jersey. Conor McGregor, a partial owner of BKFC, posted the news to his social media after an initial report by Uncrowned. Edgar's manager, Ali Abdelaziz, also confirmed the news.
