LAS VEGAS – Paulo Costa vs. Marvin Vettori is finally official after multiple weight class changes ahead of UFC Fight Night 196 . Fight week began with Costa (13-1 MMA, 5-1 UFC) vs. Vettori (17-5-1 MMA, 7-3-1 UFC) scheduled as a middleweight contest. It was then moved to a 195-pound catchweight due to Costa’s poor weight management, then just hours prior to weigh-ins, was shifted again to light heavyweight
