Ultimate Fighting Championship (UFC) is live TONIGHT (Sat., Sept. 19, 2026) with UFC 331 taking place at crypto.com Arena in Los Angeles, Ca., streaming exclusively live on Paramount+. The main event is a rematch for the UFC Flyweight title with Joshua Van vs. Alexandre Pantoja 2.
Joshua Van gets a chance to defend his UFC Flyweight title for the second time tonight when he meets former champion Alexandre Pantoja. Van was, of course, awarded the belt after Pantoja went down with an arm injury early in their first fight last year. Since then Van solidified his title as champion by beating Tatsuro Taira in one of the fights of the year. This is Pantoja's first fight back since suffering that arm injury.
The co-main event tonight is a five round non-title fight in the Lightweight division. Arman Tsarukyan vs. Mauricio Ruffy could fast-track someone to a title shot with Justin Gaethje. For Tsarukyan that would be his second title shot, if you count the one he lost on weigh-in day (due to a back injury) before he was supposed to fight Islam Makhachev. Ruffy has never been this close to a title shot, but a win here on the back of his White House demolition job on Michael Chandler would be a big statement.
The main card is rounded out by Patricio Pitbull vs. Doohoo Choi, Alonzo Menifield vs. Iwo Baraniewski and Gable Steveson vs. Sean Sharaf. This will be Pitbull's final fight on his current UFC deal. Iwo Baraniewski is worth keeping tabs on. He's won all his UFC fights so far in electrifying fashion. Steveson is, again, on course to be one of the biggest favorites in MMA betting history, that's in spite of him being just 4-0 as a pro.
The Featured 'Prelim' tonight is Marlon Vera vs. Charles Jourdain in the Bantamweight division. That portion of the card also has Robelis Despaigne vs. Tai Tuivasa, Michael Aswell vs. Joo Sang Yoo and Ryan Gandra vs. Ozzy Diaz.
The Early 'Prelims' kick us off with Giga Chikadze vs. Joanderson Brito. The early part of the show also includes Casey O'Neill vs. Eduarda Moura and Edmen Shahbazyan vs. Brunno Ferreira.
