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.

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 is the new UFC welterweight champion after beating Belal Muhammad in a sensational war of attrition at UFC 315 on Saturday night in Montreal.
