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.

Australia has a new UFC champion in Jack Della Maddalena. Della Maddalena put in a fantastic performance in the main event of UFC 315, outworking Belal Muhammad to win the UFC welterweight championship.
