This weekend, the Ultimate Fighting Championship returns to Las Vegas with a stacked UFC 323 card, headlined by a pair of championship bouts featuring two of the sport's most dominant titleholders.
Champions Defend Their Thrones in Sin City
In the main event, the seemingly unstoppable Merab Dvalishvili puts his men's bantamweight championship on the line in a highly anticipated rematch against former champion Petr Yan. Their clash at the T-Mobile Arena on Saturday 6 December 2025 comes two years after Dvalishvili outpointed Yan to cement his own title shot.
Since capturing the gold, the Georgian champion has been a force of nature. Remarkably, he is seeking his fourth consecutive title defence in just 12 months. In 2025 alone, Dvalishvili has added victories over Umar Nurmagomedov and Cory Sandhagen to his record, and also submitted the man he dethroned in 2024, Sean O'Malley.
Co-Main Event: Flyweight King Faces Youthful Challenge
The co-main event features another dominant force, as flyweight king Alexandre Pantoja aims for his fifth straight successful title defence. Standing in his way is the surging Joshua Van, a 24-year-old phenom. A victory for Van would see him crowned the youngest active champion on the UFC roster, marking a dramatic changing of the guard.
