UFC 323 will culminate in two title fights this weekend, as pound-for-pound talents Merab Dvalishvili and Alexandre Pantoja defend their belts.
In the main event in Las Vegas, Dvalishvili puts his bantamweight title on the line against Petr Yan, in a rematch two years in the making. Dvalishvili outpointed the former champion while closing in on a title shot, and the Georgian has been dominant since gaining the gold.
This weekend, remarkably, he seeks a fourth straight successful title defence in 12 months. This year, Dvalishvili has outpointed Umar Nurmagomedov and Cory Sandhagen and submitted rival Sean O’Malley, the man he dethroned in 2024.
And in UFC 323’s co-main event, another dominant champion enters the cage, seeking a fifth winning title defence in a row. Flyweight king Pantoja takes on rising star Joshua Van, 24, who could become the youngest active UFC champion with a win.
Here’s all you need to know.
