The UFC’s ‘BMF’ title returns this weekend, as Dustin Poirier and Justin Gaethje clash for the unique status of the promotion’s ‘baddest motherf*****’. Poirier stopped Gaethje in an entertaining fight in 2018, and the Americans have since gone on to win the interim lightweight belt on separate occasions, though both have come up short in two undisputed-title fights each. Now, however, they have the chance to add another accolade to their resumes. Poirier, 34, and Gaethje, also 34, will go head to head to crown a new BMF champion, with the title having previously been seen just once in the UFC – when the now-retired Jorge Masvidal beat Nate Diaz in 2019. In the co-main event of UFC 291, 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 exciting match-ups 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.
