The UFC President was asked about the rematch during the UFC Vegas 12 post-fight press conference, with White saying the fight was a done deal “as far as I know” (via MMA Fighting).
Reports have previously stated that the highly anticipated rematch would go down in January, but no official date has been confirmed at this time.
McGregor and Poirier met for the first time at UFC 178 in September of 2014, with McGregor scoring a first round TKO victory on that night. Since that first meeting, McGregor has gone on to win the UFC lightweight title and UFC featherweight title, while Poirier went on to win the UFC interim lightweight title. If the bout does come to fruition, it would mark McGregor's first bout since UFC 246, while Poirier last headlined a Fight Night card this past June.
