Diaz shocked the MMA world in March when he submitted McGregor at UFC 196 despite accepting the welterweight bout on just 11 days’ notice. McGregor, the current UFC featherweight champion, was initially slated to challenge lightweight champ Rafael Dos Anjos to try and become the promotion’s first two-way title holder in the event until dos Anjos was forced to pull out with a broken foot.
The rematch will also take place in a non-title welterweight bout.
After losing the fight, McGregor said he would most likely return to featherweight to defend his throne in his next outing.
