Dustin Poirier and Justin Gaethje will clash in the main event of UFC 291 tonight, in a rematch with the ‘BMF’ title on the line. Poirier beat Gaethje via fourth-round TKO in 2018, and the pair’s careers followed similar trajectories in the time since. Poirier, 34, won the interim lightweight title in 2019 but failed to unify the belt against Khabib Nurmagomedov, losing to the Russsian via submission; Gaethje, 34, then collected the interim gold in 2020 but was also submitted by Khabib. Each man then got a second crack at the gold but came up short again, with Poirier submitted by Charles Oliveira in 2021 and Gaethje suffering the same fate last May. However, Poirier and Gaethje have both bounced back since then, with the former stopping Michael Chandler and the latter beating Rafael Fiziev. And when Poirier and Gaethje rematch in Salt Lake City, Utah, tonight, the ‘Baddest Motherf*****’ belt will be up for grabs. The title has only appeared once before, when Jorge Masvidal beat Nate Diaz to become the inaugural champion in 2019. In this evening’s co-main event, former middleweight champion Alex Pereira moves up to light-heavyweight to face Jan Blachowicz, an ex-title holder in the division.
