Joshua Van vs Alexandre Pantoja 2 at UFC 331: What Has Changed Before the Flyweight Title Rematch

Joshua Van and Alexandre Pantoja will meet for the second time on 19 September 2026, when the UFC flyweight title is contested in the main event of UFC 331 at Crypto.com Arena in Los Angeles. Their first fight produced an official winner but almost none of the answers normally expected from a championship contest. Van took the belt at UFC 323 in December 2025 after Pantoja suffered an elbow injury only 26 seconds into the opening round. Nine months later, the situation is very different. Van has already defended his championship in a demanding five-round fight, Pantoja has completed his recovery, and their previously respectful rivalry has become noticeably more tense. The rematch is therefore not simply a repeat of a fight cut short by injury. It is a meeting between a champion who has strengthened his position and a former champion trying to prove that the unusual ending of their first bout interrupted rather than ended his reign at the top of the division.

Why the First Fight Still Needs a Proper Answer

The official record is straightforward: Joshua Van defeated Alexandre Pantoja by TKO due to injury at 26 seconds of the first round at UFC 323 on 6 December 2025. Pantoja entered that contest as the reigning flyweight champion, while Van arrived as one of the fastest-rising contenders in the division. The fight had barely started when Pantoja threw a high kick, Van caught it as the Brazilian lost his balance, and Pantoja attempted to brace himself while falling. He injured his elbow on the way down and immediately recognised that he could not continue. Van became champion, but neither fighter had enough time to establish his preferred rhythm or demonstrate how the broader match-up would develop over several rounds.

That distinction matters before UFC 331. Van did not win through a disputed judges’ decision, and the result remains a legitimate TKO victory on his record, but the circumstances make it difficult to use the first meeting as evidence of how the two compare over a normal championship fight. There was no extended striking exchange, sustained grappling sequence, lengthy period against the fence or meaningful test of endurance. Even the opening moments provide only a limited sample. Pantoja was willing to attack immediately, while Van reacted quickly enough to the kick to contribute to the sequence that ended the fight, yet 26 seconds cannot answer the larger questions surrounding their styles.

The roles have also been reversed. In December 2025, Pantoja was the established champion and Van was attempting to take his place. In September 2026, Van walks into UFC 331 with the belt while Pantoja has to regain something he held for more than two years. That creates a different type of pressure for both men. Van now has to show that his first victory was not simply the product of an unfortunate injury, while Pantoja has to prove that his previous championship run can be restarted after a long recovery. The unusual first result therefore gives the rematch an extra layer: neither man can rely on the previous bout to demonstrate clear superiority.

Van Is No Longer an Unproven Champion

The most important development since UFC 323 is what Joshua Van did in his first title defence. He faced Tatsuro Taira at UFC 328 on 9 May 2026 and was forced into a far more demanding contest than the one that made him champion. Taira repeatedly took Van down during the early part of the fight and controlled long stretches of the opening rounds. Van did not panic when the contest was going against him. He continued working back to his feet, found openings with his boxing as the fight progressed and hurt Taira late in the second round before taking greater control in the third. The championship fight eventually reached the fifth round, where Van stopped Taira with strikes at 1:32.

That performance changed the way Van can reasonably be assessed before facing Pantoja again. When he first received the belt, he had not experienced a full UFC championship fight. Against Taira, he had to cope with prolonged periods on the ground, momentum moving in both directions and the physical demands of fighting beyond three rounds. He also showed that losing the early stages did not force him to abandon his approach. His ability to remain competitive after difficult grappling exchanges and then increase his effectiveness later in the fight is particularly relevant against Pantoja, whose strongest work has often come when he can turn a contest into a physical battle at close range.

Van enters UFC 331 with a professional record of 17 wins and two losses, including nine victories by knockout or TKO. At 24, he is still unusually young for an established UFC champion, but his recent schedule has accelerated his development. Before becoming champion he defeated Brandon Royval by unanimous decision at UFC 317, and the victory over Taira then gave him something the first Pantoja fight could not: evidence that he can solve problems during a long title contest. That does not remove the danger presented by the former champion, but it means the version of Van preparing for the rematch has substantially more championship experience than the fighter who entered UFC 323.

Pantoja Returns With Recovery and Championship Experience

For Alexandre Pantoja, the months between the two fights have been shaped primarily by recovery. His elbow injury ended his title reign in a matter of seconds and kept him out of competition while Van moved forward with the division. By July 2026, Pantoja said he was healthy and ready to compete again. He has also described making changes around his preparation, including greater attention to his diet, sleep and the people involved in his training. Those details are significant because UFC 331 will be his first competitive fight since the injury. Training can establish that an arm is functional again, but a five-round title fight will provide the real test of how comfortably he can use it under pressure.

Pantoja nevertheless returns with a level of championship experience that Van has not yet accumulated. Before losing to Van, the Brazilian had successfully defended the UFC flyweight title four times, beating Brandon Royval, Steve Erceg, Kai Asakura and Kai Kara-France. His professional record stands at 30 wins and six losses, with 12 victories by submission and eight by knockout or TKO. UFC records also place him among the most successful flyweights in the history of the organisation, including the division records for total wins, finishes and submissions. His previous reign was built over several years rather than a brief run of favourable results.

The obvious contrast is age. Pantoja is 36, while Van is 24, creating a 12-year gap between challenger and champion. It would be too simple, however, to treat that difference as proof that the younger fighter automatically has the advantage. Pantoja was on an eight-fight winning streak before the injury loss, and his four consecutive title defences showed that he could repeatedly prepare for elite opponents with different strengths. The more relevant uncertainty is inactivity. Van has completed an intense five-round fight during Pantoja’s absence, while Pantoja has spent much of the same period recovering. UFC 331 will show whether that break left him fresher or whether competitive sharpness becomes a factor after nine months without a completed bout.

How the Match-Up Has Changed Since December

At a basic level, their strengths remain easy to distinguish without reducing either man to a single skill. Van is most comfortable when he can build combinations with his hands, maintain a steady striking output and force opponents to keep reacting as a round develops. Pantoja has dangerous striking of his own, but his greatest threat is the way he can connect striking exchanges with clinches, takedowns and submission attempts. He has 12 submission victories in professional MMA and has repeatedly shown that giving him a strong position on the ground can turn a competitive round into an immediate defensive problem.

Van’s fight with Taira has made the grappling side of the rematch more interesting. Taira had considerable early success taking the champion down, yet Van repeatedly found ways to stand and remained dangerous after those difficult periods. That does not mean success against Taira automatically translates to success against Pantoja. Their grappling approaches are not identical, and Pantoja brings years of experience against championship-level opposition. What Van proved in May is that being taken down does not necessarily remove him from a fight. Pantoja may therefore need more than isolated takedowns; keeping the champion in bad positions and making those exchanges costly could be much more important.

Pantoja also has reasons to avoid treating the contest as a simple return to his old formula. Van has now shown that he can remain patient through difficult rounds and still produce a late stoppage. Allowing the champion to settle into a comfortable striking rhythm could become increasingly dangerous as the fight progresses. At the same time, Van cannot assume that defending Taira’s attacks means he can comfortably accept extended grappling exchanges with Pantoja. The first meeting did not test any of these questions. The second is likely to be decided by which fighter can impose his preferred type of fight without allowing the other to settle into a sustained rhythm.

What UFC 331 Means for the Flyweight Division

UFC 331 takes place on Saturday, 19 September 2026, at Crypto.com Arena in Los Angeles, with Van versus Pantoja 2 scheduled as the main event for the flyweight championship. The billing itself reflects how much has changed since their first meeting, which appeared beneath the main event at UFC 323. Van is now presented as the division’s champion rather than its emerging challenger, while Pantoja returns as the number-one-ranked contender attempting to regain the title. A fight that initially represented Van’s attempt to break into the established order has become a contest over whether that change of order is permanent.

The age difference gives the fight wider significance as well. Van belongs to a younger group of flyweights who have moved quickly towards the top of the division, and his defence against 26-year-old Taira underlined that transition. A second victory over Pantoja would strengthen the case that the championship picture has genuinely moved into a new phase. It would also give Van two successful title defences within his first year as champion and remove much of the uncertainty created by the accidental nature of the first fight. He would no longer be judged primarily on the 26-second result at UFC 323 because he would have beaten the former champion again in a completely separate contest.

A Pantoja victory would create a different story. He is attempting to become only the third fighter in UFC flyweight history to regain the championship after losing it, following Brandon Moreno and Deiveson Figueiredo. Reclaiming the belt at 36 after an injury-enforced absence would also extend a period in which Pantoja has remained connected to the division’s most important fights for years. More importantly, it would show that the title change in December did not mark the end of his ability to compete at the highest level. The result will therefore affect more than the rivalry itself: it will help determine whether the division continues towards a younger champion-led era or returns to one of its most accomplished recent titleholders.

The Factors That Matter Most on 19 September

For Van, the central challenge is to combine the confidence gained against Taira with the discipline required against a more experienced former champion. His first title defence showed that he can recover from difficult positions, but repeatedly allowing Pantoja to establish control would still be dangerous. Van is at his best when he has enough space to work consistently, increase his output and make an opponent react to combinations. The longer he can keep those exchanges in areas where he is comfortable, the more opportunities he should have to use the speed, timing and late-round persistence that have become important parts of his rise.

For Pantoja, physical readiness after the elbow injury is only one part of the question. His ability to re-establish the pressure that defined his championship run may matter just as much. He has said that his preparation is better organised now, with more attention given to recovery, diet and sleep. UFC 331 will reveal how those changes translate into competition. The challenger does not need to prove that the first injury was a freak occurrence; that is already clear from the way the bout ended. He needs to show that after recovery he can again perform at the level that produced four consecutive successful title defences.

The atmosphere around the rematch has changed too. The build-up to their first fight was comparatively respectful, while the UFC 331 press conference in August became heated enough that the fighters had to be separated during an exchange. That tension adds emotion, but the actual contest will still depend on decisions made inside the cage rather than comments made beforehand. Van arrives as a champion who has now earned a full championship victory under difficult conditions. Pantoja arrives healthy, experienced and determined to regain the belt he lost through injury. Because their first meeting lasted only 26 seconds, UFC 331 effectively provides the first extended opportunity to judge which of them is better prepared to lead the flyweight division in 2026.
