Costa has emerged as the next man up at 185 pounds. He owns 11 career knockouts including four in the UFC 253 Live Free. The beef between he and Adesanya has steadily grown as fight night approaches. But when Jones announced that he was vacating his belt, the UFC decided to match up the two frontrunners to fight for the vacant title, and Blachowicz says Reyes is a very worthy opponent. Reyes (12-1 MMA, 6-1 UFC) took Jones to the brink in February in a fight that many, including Dana White, scored in his favor. Prior to that, he knocked out former UFC middleweight champion Chris Weidman in less than two minutes.
