Conor McGregor knocked out Dustin Poirier in 2014. Poirier got revenge with a knockout this past January. On Saturday night, the two will settle their trilogy in the main event of UFC 264 in Las Vegas.
The bout, which UFC president Dana White has said will lead to a lightweight title shot for the winner, headlines a night of fights before a full house at T-Mobile Arena, making it the UFC's first event in its hometown arena since March 2020. The promotion has been putting on shows without fans in attendance at its small UFC Apex venue.
The main card will be on pay-per-view, which fans can purchase here. The five-fight PPV card begins at 10 p.m. ET, with prelims on ESPN and ESPN+ starting at 8 p.m. ET and early prelims on ESPN and ESPN+ at 6 p.m. ET.
Poirier (27-6, 1 NC) has lost only one of his past nine fights, and that was to the champion at the time, the indomitable Khabib Nurmagomedov. He is No. 6 in the ESPN men's pound-for-pound rankings and No. 2 in the lightweight top 10, behind only champion Charles Oliveira.
McGregor (22-5) was the UFC's first double champ, reigning simultaneously at featherweight and lightweight. But he has competed only three times since 2016, and lost two of those bouts.
