UPDATED UFC 291 Weigh-in Results: Thompson vs. Pereira Canceled

Editor's note: The article has been updated at 6:55 p.m. ET to reflect the cancelation of one of the main card matchups.

The Ultimate Fighting Championship's "BMF Championship" will be on the line for the second time at UFC 291.

Vying to be the promotion's "baddest MFer" are former interim lightweight champions Dustin Poirier and Justin Gaethje. Both men came prepared and looked sharp during the weigh-ins, as "The Diamond" weighed 155 pounds on the dot, while Gaethje came in at 156 pounds.

Two fighters failed to make weight for the card. The most notable miss came from Michel Pereira, who checked in at 174 pounds for his welterweight match against Stephen Thompson. Shortly before the ceremonial weigh-in show, the UFC announced that the fight has been canceled. The promotion has listed on its website that the heavyweight scrap between Derrick Lewis and Marcos Rogerio de Lima has been elevated to the main card. Additionally, Vinicius Salvador came in at 128.5 pounds for his flyweight contest against C.J. Vergara. As a result of being 2.5 pounds over the limit, Salvador has been fined 20% of his purse..

This marks the first fight of the year for Poirier (29-7, 1 NC). The fan-favorite is coming off a rear-naked choke win over Michael Chandler, which served as a bounce-back performance after losing via the same submission to then-champion Charles Oliveira. Prior to the defeat, the Louisiana native had won three straight, including two wins over Conor McGregor.

Meanwhile, "The Highlight" got back on the winning track after his own RNC loss to Oliveira by winning a majority decision over Rafael Fiziev earlier this year. This marks the first time that Gaethje has fought twice in a year since 2020. His other recent victory was an all-out war against Michael Chandler that saw Gaethje earn a unanimous decision.

The UFC 291 main card will air live on ESPN+ pay-per-view at 10 p.m. ET/7 p.m. PT on Saturday. Prelims begin on ESPN+ and UFC Fight Pass at 6:30 p.m. ET/3:30 p.m. PT before transitioning to ABC, ESPN and ESPN+ at 8 p.m. ET/5 p.m. PT.
