UFC 331 is scheduled for 19 September 2026 at the Crypto.com Arena in Los Angeles, with live streaming available on Paramount+. The main event features a flyweight championship rematch between champion Joshua Van and former champion Alexandre Pantoja. Their previous bout at UFC 323 ended after only 26 seconds when Pantoja suffered a shoulder injury, resulting in a TKO victory for Van.

During a press conference in Philadelphia, the two fighters engaged in a heated confrontation. Van dismissed the impact of the previous injury, stating, “Had that not happened, I would still whup his ass that day.” Pantoja responded by telling Van to “wash his mouth,” adding that in Brazil, people must be careful about what they say. This led to a physical escalation where security had to restrain Pantoja.

Van enters the rematch with a 17-2 record, having successfully defended his title once against Tatsuro Taira. He noted that a previous knockout loss to Charles Johnson humbled him and prompted an overhaul of his training and work ethic.

The co-main event features lightweight contender Arman Tsarukyan against Brazilian Mauricio Ruffy. The winner is slated to face champion Justin Gaethje next year. Ruffy, who trains in Australia under Alexander Volkanovski, has expressed his desire for a knockout victory. The card also includes matchups such as Renato Moicano vs. Brian Ortega 2 and Patricio Pitbull vs. Doo Ho Choi.
