The official fight order for UFC 323, scheduled for December 6 at T-Mobile Arena in Las Vegas, has been confirmed. The main event features a highly anticipated bantamweight rematch between Merab Dvalishvili and Petr Yan, with Dvalishvili aiming to defend his title for the fourth time this year. Dvalishvili has an impressive winning streak of 14 fights, having defeated Umar Nurmagomedov, Sean O’Malley, and Cory Sandhagen in 2025. Yan, a former bantamweight champion, is on a three-fight winning streak and previously lost to Dvalishvili in March 2023. Analysts suggest Yan could improve his chances by reducing takedown attempts, especially by avoiding excessive takedowns and improving fight strategy, including better footwork and defensive techniques. Yan is currently a sizable betting underdog for the rematch. The fight card also includes Alexandre Pantoja defending his flyweight title against Joshua Van, along with other bouts. The event will be broadcast via pay-per-view on ESPN+ and prelims on ESPN2/ESPN+.
