UFC 331 is official after flyweight champion Joshua Van and former champion Alexandre Pantoja both weighed 125 pounds Friday in Los Angeles. Every fighter scheduled for Saturday's 12-bout card made weight.
The title rematch
Van and Pantoja will meet again after their first fight ended just 26 seconds into UFC 323 when Pantoja suffered an arm injury. Van has since defended the belt against Tatsuro Taira, while Pantoja returns with a chance to reclaim the championship he lost under unusual circumstances.
The matchup also brings a sharp contrast in age and pace. Van, 24, enters with a 17-2 record and one of the division's highest striking outputs. Pantoja, 36, is 30-6 and remains one of the most accomplished grapplers at 125 pounds.
The rest of the main card
Arman Tsarukyan weighed 156 pounds for the five-round lightweight co-main event against Mauricio Ruffy, who came in at 155. Patricio Pitbull faces Doo Ho Choi at featherweight, Gable Steveson meets Sean Sharaf at heavyweight, and Alonzo Menifield takes on unbeaten Iwo Baraniewski at light heavyweight.
Early prelims begin Saturday at 5:30 p.m. ET, followed by the prelims at 7 p.m. and the main card at 9 p.m. on Paramount+.
