Important ranking positions at the top of the UFC’s middleweight division will be on the line at UFC 224 as No.2 Jacare Souza will face No.5 Kelvin Gastelum at the May 12th PPV event.

Souza defeated Derek Brunson in his last outing, a January 27th TKO victory at UFC Fight Night Charlotte.

The 38-year-old has won three of his last four bouts with triumphs over Tim Boetsch and Vitor Belfort and a setback against Robert Whittaker on his recent record.  He has an overall MMA mark of 25-5 (1)

Kelvin Gastelum beat former champion Michael Bisping via KO at Fight Night Shanghai last November.

Prior to that, he dropped a third round submission to another former champion, Chris Weidman, at Fight Night Uniondale.

A bout between Belfort and Lyoto Machida has also been announced for the Rio de Janeiro, Brazil event that will take place at the Jeunesse Arena.
