Joshua Van to Rematch Alexandre Pantoja for Flyweight Title at UFC 331 in Los Angeles

On September 19, 2026, Joshua Van and Alexandre Pantoja will step into the octagon at Crypto.com Arena in Los Angeles to finally answer the question that has hung over the UFC flyweight division for months. Van, the reigning 125-pound champion, will defend his belt against Pantoja, the former kingpin, in the main event of UFC 331. The bout promises to settle a score that was left agonizingly unresolved earlier this year.[1][2]

The stakes are immense, built entirely on the unresolved tension of their first encounter. At UFC 323, the highly anticipated changing-of-the-guard matchup ended in a devastating anticlimax. Just 26 seconds into the opening round, Pantoja suffered a severe elbow injury, forcing an immediate stoppage and crowning Van the new champion by default.[2][4]

In the brutal calculus of mixed martial arts, an injury stoppage is a definitive win on paper, but it leaves a lingering asterisk in the minds of fans and fighters alike. Van left the arena with the gold, but without the satisfaction of having truly bested the division's boogeyman in a full contest. Pantoja left without his belt, sidelined by a freak mechanical failure of his own body rather than a tactical defeat.[5][6]

Now, the UFC is running it back, utilizing its standard mechanism for resolving disputed or injury-shortened title fights: the immediate rematch. This booking philosophy ensures that championship lineages remain undisputed and that fighters who lose their titles to freak occurrences get a fair chance to reclaim them once healthy.[6]

For the 36-year-old Pantoja, UFC 331 represents a historic opportunity. Before the injury, the Brazilian veteran had assembled a dominant reign, defending the flyweight title four consecutive times against top-tier contenders including Brandon Royval, Steve Erceg, Kai Asakura, and Kai Kara-France.[2]

If Pantoja can secure the victory in Los Angeles, he will become only the third flyweight in UFC history to reclaim the championship after losing it, joining the elite company of Brandon Moreno and Deiveson Figueiredo. It is a legacy-defining moment for a fighter entering the twilight of his athletic prime.[2][4]

Joshua Van, however, has not been waiting idly for Pantoja to heal. The young champion validated his status at UFC 328 in May, defending the flyweight crown with a spectacular fifth-round technical knockout over rising undefeated Japanese star Tatsuro Taira.[2]

That performance proved Van is not merely a placeholder champion. By weathering Taira's grappling and drowning him in late-round pressure, Van demonstrated the championship mettle required to hold the 125-pound throne. He enters the rematch with the confidence of a proven titleholder, eager to erase the asterisk of his initial victory over Pantoja.[5][6]

The stylistic matchup remains as compelling as it was the first time around. Van is a pressure-heavy striker who thrives on overwhelming volume and suffocating pace. Pantoja is a chaotic, durable grappler with heavy hands and a knack for turning fights into grueling, high-paced scrambles.[6]

Adding to the magnitude of the event is the location. UFC 331 marks the promotion's highly anticipated return to Los Angeles, a city that has not hosted an octagon event since UFC 227 in August 2018.[1][3]

The eight-year absence from the 'City of Stars' makes this a marquee destination event for the UFC. Crypto.com Arena will host a stacked card designed to deliver maximum entertainment value to the Southern California market, which has long been a foundational stronghold for mixed martial arts.[3][4]

The co-main event further elevates the stakes of the evening. Number two-ranked lightweight contender Arman Tsarukyan will face surging knockout artist Mauricio Ruffy in a five-round bout with massive title implications at 155 pounds.[2][3]

Tsarukyan enters on a five-fight winning streak, including a pivotal victory over former champion Charles Oliveira at UFC 300, while Ruffy looks to capitalize on the momentum of a highlight-reel knockout over Michael Chandler in June.[2]

The uncertainty surrounding the main event is what makes it a must-watch. Can Pantoja's 36-year-old body withstand the grueling pace of a five-round title fight after a major elbow injury? Will Van's youth, speed, and recent active schedule give him an insurmountable edge over the returning veteran?[5][6]

Ultimately, UFC 331 is a story of resilience and validation. For Pantoja, it is the chance to prove his body hasn't betrayed him and his era isn't over. For Van, it is the opportunity to definitively conquer the ghost of the previous champion and cement his own legacy at the top of the flyweight division.[6]
