Dustin Poirier and Justin Gaethje will clash to crown a new ‘BMF’ champion at UFC 291, in what could be the fight of the year. Five years after Poirier stopped Gaethje in a thrilling bout, the Americans will square off again, with the vacant ‘baddest motherf*****’ belt on the line in Utah. Since their first in-ring meeting, the lightweights have lost two undisputed-title fights each, but both men have crafted impressive resumes nonetheless. And Poirier, 34, and Gaethje, also 34, will look to bolster those resumes here, as they fight for the BMF title, which has only been on the line once before. In 2019, the now-retired Jorge Masvidal beat Nate Diaz to become the inaugural champion. In the co-main event this weekend, former light-heavyweight champion Jan Blachowicz welcomes Alex Pereira to the division, in the latter’s first fight since losing the middleweight belt in April. Elsewhere, there are plenty of great fights on the card. Here’s all you need to know. When is it? UFC 291 takes place at the Vivint Arena in Salt Lake City, Utah, on Saturday 29 July.
