This weekend, Dustin Poirier and Justin Gaethje will go head to head in a rematch five years in the making, as they headline UFC 291. When the lightweights clashed in 2018, Poirier stopped his fellow American to win an entertaining bout, and the pair are expected to produce more fireworks this weekend, as they fight to crown a new ‘BMF’ champion. The ‘baddest motherf*****’ title was first – and last – seen in 2019, when the now-retired Jorge Masvidal beat Nate Diaz to become the inaugural champion. Masvidal’s teammmate Poirier will now look to claim that vacant belt in this rematch with Gaethje, who is a former interim lightweight champion like his rival. 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 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.
