Pico (13-5 MMA, 0-1 UFC) took the fight against featherweight replacement opponent Lerone Murphy (17-0-1 MMA, 9-0-1 UFC), who stepped in for Movsar Evloev on just about three weeks' notice. He had won nine of his past 10 Bellator fights before that promotion was shuttered by the PFL, and the one loss was from an injury.

UFC 319 was a dramatic affair from Chicago, Illinois, with a 12-fight card headlined by Dricus du Plessis and the newly-crowned champion Khamzat Chimaev. The main card saw back-to-back knockouts come by spinning elbow as Carlos Prates KO’d Geoff Neal, and the undefeated Lerone Murphy spoiled Aaron Pico’s UFC debut in brutal fashion.
