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.

Aaron Pico's long-awaited UFC debut came with the possibility of an immediate title shot with a win. Instead, the former uber prospect and Bellator MMA star was knocked out cold in spectacular and violent fashion at UFC 319 in Chicago .

Lerone Murphy kept his unbeaten record intact and further established himself as a featherweight contender with a first-round knockout win over Aaron Pico in the co-main event of UFC 319.
