Conor McGregor seeks to regain his throne atop the MMA world with a victory against Dustin Poirier in the main event of UFC 264.
A win is a necessity for Poirier (27-6, 1 NC) in order to challenge lightweight champion Charles Oliveira. If McGregor (22-5) loses, he can pivot quite easily to a trilogy fight against Nate Diaz (and a victory there may be enough to reinsert McGregor back into title contention). Win or lose against Poirier at 264, McGregor has another big fight looming against Michael Chandler. Poirier, however, takes a step or two down the rung of relevancy with a loss to McGregor.
