UFC 291 takes place at Delta Center in Salt Lake City. After preliminary card fights on ESPN+ (7 p.m. ET) and then ABC  and ESPN (8 p.m. ET), the UFC 291 main card streams on ESPN+ PPV at 10 p.m. ET.

According to the latest UFC 291 odds as of fight day on Saturday, Poirier is a -152 favorite (bet $152 to win $100), which translates to an implied win probability of 60.3%. Gaethje is a small +128 underdog (bet $100 to win $128). The total for the five-round fight is set at 2.5 rounds (-142 over/+112 under).

The veteran lightweights first met in 2018, when Poirier scored a fourth-round TKO victory over Gaethje in a classic bout. Now, for the rematch at UFC 291 this weekend, the unofficial "BMF title" is on the line.

A planned UFC 291 main-card bout between welterweights Stephen Thompson and Michel Pereira was canceled on Friday after Pereira missed weight by three pounds (174).
