Jack Della Maddalena? And new. Alexander Volkanovski? And again. Della Maddalena and Volkanovski took care of business in their respective title fights at UFC 315 and UFC 314, with Della Maddalena dethroning welterweight champion Belal Muhammad and Volkanovski claiming a vacant featherweight title to become two-time champion with a hard-fought win over Diego Lopes.

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.

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.
