Former two-division UFC champion Alex Pereira offered a blunt assessment of the UFC 327 main event, where New Zealand’s Carlos Ulberg knocked out Jiri Prochazka in the first round to claim the vacant light heavyweight title.
Alex Pereira didn’t hold back after UFC 327, where Carlos Ulberg stopped Jiri Prochazka in the first round on April 11 in Miami to win the vacant light heavyweight championship. The result immediately reshaped the 205-pound title picture, with Ulberg emerging as a serious new force in one of the UFC’s thinnest but most volatile divisions.
The main event turned chaotic fast. Ulberg appeared to injure his leg early in the fight, but still flipped the momentum and finished the Czech contender with a left hook and follow-up shots at 3:45 of Round 1.
Speaking to MMA Fighting, Pereira — who previously vacated the 205-pound belt to pursue an interim heavyweight title fight — was critical of his former opponent’s approach.
“Everybody saw that Ulberg was hurt. Maybe he came in with issues, or maybe the leg kicks caused the injury. That doesn’t matter. The responsibility is always on the fighter — he is the one responsible for his own health.
“It seemed to me that Jiri was charging forward very aggressively. He looked a little different in the Octagon than usual. It felt like he paid the price for that samurai mentality. I probably would have fought differently. There’s no point in feeling sorry for your opponent — you’re already trying to hurt each other. Jiri paid heavily for his actions. I think he’ll learn from those mistakes.”
For Ulberg, the win could set up a run of fresh matchups at the top of the division, especially if Pereira returns to 205 pounds after his heavyweight detour. For Prochazka, the loss raises new questions about whether his all-action style can still carry him through elite opposition when the margins are this thin.
American fans have long embraced Prochazka’s chaos-first approach, but this was the downside of it: one mistake against a composed, accurate striker can end the night instantly. Ulberg’s rise also adds another high-level kickboxing threat to a division Pereira once ruled. Now the focus shifts to whether Ulberg can defend the belt against a proven former champion — and whether Prochazka can adjust before another title run slips away.
