In the co-main event, Jan Błachowicz (27-8 MMA, 10-5 UFC) defeated Dominick Reyes (12-2 MMA, 6-2 UFC) by TKO at four minutes in the second round of the UFC light-heavyweight championship bout for the vacant title after former two-time champion Jon Jones vacated the belt on August 17, to compete in the heavyweight division. After controlling most of the action in a slow first round, Blachowicz apparently broke Reyes' nose during the second round, and he abruptly ended it when he landed a high left hook to the side of Reyes' head.
