LOS ANGELES, CALIFORNIA - SEPTEMBER 19: Joshua Van of Myanmar reacts after a victory against Alexandre Pantoja of Brazil in the UFC flyweight championship fight during the UFC 331 event at Crypto.com Arena on September 19, 2026 in Los Angeles, California. (Photo by Chris Unger/Zuffa LLC) UFC 331 went down last night (Sat., Sept. 19, 2026) inside Crypto.com arena in Los Angeles, Calif., which saw Joshua Van defend his UFC Flyweight by defeating Alexandre Pantoja via unanimous decision in an absolute classic (scorecards here). In the co-main event, Arman Tsarukyan made an emphatic statement by knocking out Mauricio Ruffy with a massive elbow with just four seconds left in the first round, making a great case for himself for a championship fight (see it again here). In further action, Sean Sharaf delivered the biggest upset of the night by knocking out Gable Steveson in just 12 seconds (see it again here). Biggest Winner: Sean Sharaf This one is no shocker. Sharaf came in as the massive underdog against the man many were looking at as the potential future of the Heavyweight division, Gable Steveson. But in the blink of an eye, Sharaf — a United States Marine — tagged Steveson with a massive left hook that knocked the Olympic gold medalist out cold, ending the hype before it picked up more steam, all while giving him the biggest win of his MMA career 12 seconds into the fight. Sharaf now has the third fasted knockout in the history of the 265-pound weight class. To make it even sweeter, Sharaf was 0-2 inside the Octagon coming into the event, so to secure his first win under the UFC banner against one of the most hyped fighters in the company is going to be a tough moment to beat. And that post-fight bonus cash only sweetens the pot. Runner (s) Up: Joshua Van and Arman Tsarukyan Van was looking for a more definitive win over Pantoja in their championship rematch, and he got it. While he didn’t get the finish, Van put one one heck of a performance against the Brazilian challenger, who came out of the games like a bat out of hell eager to set the pace of the fight on his quest to reclaiming the strap. But Van didn’t lose his cool, he kept his composure and started to take over as the fight went on thanks to his crisp and precise striking. In the fifth and final round, Van took over by letting his fists fly freely, and they connected more often than not, battering and already-busted up Pantoja to lock down a unanimous decision win. At just 24 years of age van now has two title defenses and his stock is only climbing. On any other night Tsarukyan’s knockout win over Ruffy would take the top spot, but he’ll have to settle for second due to Sharaf’s massive upset. Nevertheless, Tsarukyan may have won the bigger prize because he undoubtedly locked down the next shot at Justin Gaethje’s title (sorry, Ilia) with a monstrous finish over Ruffy. Dana White wasn’t too convinced prior to the fight that a win would get Tsarukyan his dream fight, but now even he can’t deny him. Fans have been wanting to see Tsarukyan back in action instead of dominating RAF, and he made the wait worth the while. Honorable Mention: Alonzo Menifield Menifield secured one of the biggest wins of his surging career by handing Iwo Baraniewski in a back-and-forth war. Baraniewski was the slight favorite coming into the bout since he had won all of his fights in the very first round. And things were looking up for him early, tagging Menifield several times to not only get his attention, but rock him pretty good. But Menifield showed his toughness and weathered the early storm to become the first man to take Iwo out of the first round. In round two, Menifield suffered a gnarly thumb injury that put him at a disadvantage. Undeterred, he sucked it up, dug dip and pulled off a massive split-decision win. He is now 4-1 in his last five and could see a climb in the rankings. Biggest Loser: Gable Steveson Again, this one shouldn’t come as a shocker. Steveson came into his second UFC hype with a ton of hype, and as the heavy favorite against a man who had lost his first two fights inside the Octagon. As a result of his first two defeats, no one was giving Sharaf a chance to beat the Olympic gold medal winner. But Steveson’s momentum and hype came crashing down just 12 seconds into the fight after he was tagged with a massive left hook that knocked him out cold before he hit the canvas. And just like that, the train is derailed, his momentum is gone and it’s going to sting for a while. To make matters worse, Steveson was criticized by the UFC commentary team for walking out the cage before Sharaf was announced the winner. But Steveson can take this is a valuable lesson for what is going to be a lengthy career. For complete UFC 331 results, coverage, and highlights click HERE.
