Two of the very best pound-for-pound fighters in the world today will be back in action tomorrow night (Sat., Dec. 6, 2025) at UFC 323 LIVE on ESPN+ pay-per-view (PPV) from inside T-Mobile Arena in Las Vegas, Nevada, as UFC bantamweight champion Merab Dvalishvili and UFC flyweight champion Alexandre Pantoja both put their titles on the line.
Dvalishvili, who can make UFC history this weekend with his fourth-straight title defense of 2025, is a heavy betting favorite to walk out of “Sin City” with his title in tow. “Machine” will be matched up against former opponent, Petr Yan, who has won his last three trips to the cage. It’s safe to say the two bantamweights don’t like one another.
Pantoja, on the other hand, will look to lock down his fifth-straight UFC title defense in a co-headliner against red-hot contender Joshua Van. Many believe Pantoja’s experience, durability, and world-class grappling game will be too much for Van, but if Van can stay on his feet he has more than just a puncher’s chance to become UFC’s new flyweight king heading into 2026.
Luckily, the action doesn’t stop there. UFC 323’s main card and “Prelims” undercard will feature the likes of former UFC champions Brandon Moreno, Henry Cejudo, and Jan Blachowicz, as well as rising stars such as Payton Talbott, Maycee Barber, Tatsuro Taira, and Terrance McKinney.
All fighters took to the stage on Friday for UFC 323’s ceremonial weigh ins. Check out some of the most memorable staredowns below and let us know your final thoughts!
