Conor McGregor has agreed to return to the UFC for a rematch with Dustin Poirier on Jan. 23 at UFC 257.
UFC President Dana White confirmed to The Associated Press that McGregor has officially signed an agreement for a probable 155-pound fight with Poirier, ending his latest retirement from mixed martial arts.
White hasn't decided whether UFC 257 will be held in Las Vegas or in the UFC's coronavirus-secure environment in Abu Dhabi. McGregor has fought in the UFC cage just twice since November 2016.
