Tonight's UFC 291 sees the much-anticipated second fight between two former interim UFC lightweight champions, as Dustin Poirier faces off against Justin Gaethje.
Poirier came out on top the first time the two fighters met back in 2018, securing a fourth-round victory by TKO.
Neither fighter currently holds the UFC lightweight belt, with Poirier and Gaethje ranked second and third in the division respectively.
And while the lightweight title will not be up for grabs tonight, the winner will put themselves one step closer to a shot at it, and win the UFC'S 'BMF' belt in the process.
