Muhammad leaves Montreal without the title he won in July by defeating Leon Edwards at UFC 304. The result also marked Muhammad's first loss since a unanimous decision against Geoff Neal in January 2019, ending a 10-fight winning streak, which also included a no contest against Edwards.

Jack Della Maddalena completely changed his career in the main event of UFC 315 — and it's possible the best is yet to come. The Australian challenged Belal Muhammad for the UFC Welterweight title — the title once held by French-Canadian legend Georges St-Pierre — in the main event at a raucous Bell Centre in Montreal.

Della Maddalena (18-2 MMA, 8-0 UFC) returned from a career-long injury layoff and thrived in his underdog role with a unanimous decision victory over Muhammad (24-4 MMA, 15-4 UFC) at Bell Centre in Montreal to become the 13th undisputed champion in divisional history.
