After weeks of rumors, it looks like word of a Diaz-McGregor rematch really is true. The two men will headline the upcoming UFC 200 card in a five-round welterweight bout.

Diaz and McGregor fought at 170lb – two weight classes above the featherweight division where McGregor is champion – at UFC 196 on March 5th. Conor was originally scheduled to meet lightweight champ Rafael dos Anjos in a 155lb title bout at the event, but RDA pulled out with injury less than two weeks before the fight and was replaced by Diaz at a higher weight. The fight was competitive and action-packed, with Diaz winning via second-round submission.

According to UFC president Dana White, McGregor was “obsessed” with the idea of getting another shot at Diaz at 170lb after suffering his first UFC loss. Despite protests from UFC bosses and his head coach, John Kavanagh, it seems the Irish champ was insistent enough to get his wish.

Also on the July 9th UFC 200 card, Frankie Edgar and former 145lb champ Jose Aldo will meet in an interim featherweight title bout. According to White, regardless of the result of Diaz-McGregor 2, McGregor will meet the winner of Aldo-Edgar in a title unification bout in his next fight after UFC 200. Aldo and Edgar first met back at UFC 156 when Aldo held the featherweight title. Ado won the fight via unanimous decision.

UFC 200 takes place at the new T-Mobile Arena in Las Vegas, Nevada.
