Ronaldo Souza and Kelvin Gastelum on Saturday in Rio de Janeiro will co-headline UFC 224 in a three-round battle that could decide the next No. 1 contender for the Ultimate Fighting Championship middleweight crown.
After losing to current champion Robert Whittaker, Souza returned to the win column with a dominant performance against Derek Brunson in January. Gastelum, meanwhile, looked better than ever in his most recent appearance, as he knocked out former 185-pound titleholder Michael Bisping on Nov. 25.
With Whittaker set to defend his championship against Yoel Romero at UFC 225, the Souza-Gastelum confrontation takes on added importance.
