He last competed on the PFL Challenger Series in February, when he laid claim to a unanimous decision over Antonio Caruso across three rounds. Aubin-Mercier, meanwhile, has rattled off seven consecutive victories. The Tristar Gym rep last fought on April 14, when he outpointed Shange Burgos to a unanimous verdict at PFL 3.
