UFC 331 poster unveiled for Joshua Van vs. Alexandre Pantoja 2 at Crypto.com Arena on Sept. 19

Ultimate Fighting Championship promotional materials for UFC 331 have arrived, and the center of the card is clear: Joshua Van will defend his UFC Flyweight title against Alexandre Pantoja in a rematch on Saturday, Sept. 19, 2026. The event is scheduled to take place inside Arena in Los Angeles, California, using the “Van vs. Pantoja 2” matchup as the headline feature of the evening.

The bout is framed as “unfinished business,” a storyline that matters in the sport because flyweight has been defined by rapid shifts in momentum, frequent title changes, and stylistic matchups that can flip quickly. For Van, the rematch carries added weight because the announcement describes this defense as his second title defense as champion, indicating that the UFC views him as a short-list main-event anchor at 125 pounds.

Pantoja, meanwhile, is introduced in the promotional coverage as a former 125-pound kingpin, a reference to his history of holding the belt at bantam-to-flyweight territory and operating at an elite level in the division. A return against a reigning champion creates immediate stakes for Pantoja’s place in the title picture, because rematches often determine whether a challenger’s adjustments translate into a long-term claim or whether the champion’s style remains the decisive factor.

The location also sets context for the event. Arena, formerly known as Staples Center, has a history of hosting major UFC cards with strong mainstream visibility in Los Angeles. By staging UFC 331 in that setting, the organization is leaning into a national spotlight, particularly for a flyweight championship fight, a division that draws dedicated audiences but typically benefits most from clear promotional emphasis on the title stakes.

While the main event is fully identified in the poster coverage, the rest of the card remains less specific in the available details. The same report notes a co-main event, but the information is truncated and not fully stated in the published description, so it would be premature to outline additional matchups or roles without confirmed reporting from UFC or the fighters’ official channels.

What to watch next is confirmation and expansion of the full card as promotional releases continue and weigh-in logistics become clearer. For fight week narratives, the key question will be how both camps approach a second meeting, because at this level, a rematch can turn on small tactical changes such as entry timing, wrestling thresholds, and how fighters manage distance under pressure. If Van is entering his second defense as champion, the expectation is that the UFC wants a fight that meaningfully tests him, not just a ceremonial defense, and Pantoja’s presence suggests the matchup is built to produce real title-picture consequence.
