The UFC returned to the “fight capital of the world” for the promotion’s final pay-per-view event of 2025, UFC 323, at T-Mobile Arena in Las Vegas on Saturday night.

Joshua Van is the new men’s flyweight champion, but not in the way he probably hoped or expected. Longtime champion Alexandre Pantoja suffered an arm injury seconds into the co-main event while defending a takedown. It was immediately clear Pantoja would not be able to continue, and the referee called the fight.

The UFC 323 prelims featured several highlight-reel knockouts, including a late entry for fight of the year between Iwo Baraniewski and Ibo Aslan, and the main card began with a rare majority draw. Double champion Henry Cejudo then officially retired from competition after a hard-fought loss to Payton Talbott.

Still to come, the UFC’s most active champion, Merab Dvalishvili, puts his men’s bantamweight belt on the line in a rematch against Petr Yan. Dvalishvili has successfully defended his championship three times this year. Yan, who lost to Dvalishvili by unanimous decision in March 2023, has not lost since facing the champ. He is on a three-fight winning streak since.

Stick around as Brett Okamoto, Jeff Wagenheim, Andres Hale and Dre Waters break down all the action at UFC 323.
