UFC 327 results: Carlos Ulberg shockingly KOs Jiri Prochazka to win title on one leg after blowing out knee

On a night full of wild and outright absurd outcomes, Carlos Ulberg saved the wildest for last. The 35-year-old Kiwi captured the vacant UFC light heavyweight championship in shocking fashion Saturday, knocking Jiri Prochazka out cold in the first round of UFC 327's main event despite suffering a blown-out right knee in the opening minute inside Miami's Kaseya Center.

After seemingly being on the verge of losing, Ulberg (14-1) flattened a surging Prochazka (32-6-1) with a monster counter left hook, then rained devastation upon the former champ in one of the most stunning scenes in recent UFC history. The official time of the stoppage came at 3:45 of the opening round.

"I blew out my knee, but I never, ever counted myself out," Ulberg said. "I knew that all I need was that one shot, and I ended up getting it."

"I've got to sort this knee out," he added. "But I'm a world champion."

Replays appeared to show Ulberg injuring the knee while retreating from a Prochazka attack in the opening exchanges of Saturday's title bout.

Prochazka picked up on the situation immediately, volleying low kick after low kick into Ulberg's legs and causing the injured New Zealander to stumble around the ring in repeated attempts to catch his balance.

Yet just as a Prochazka's second reign as UFC light heavyweight champion seemed to be near, Ulberg steeled himself against the fence and caught Prochazka with the perfect shot, leaving him in shock.

"Man, f*** — it happened," said a near-speechless Prochazka. "It's true, I felt like mercy, you know, in that fight. I felt so sorry for him.

"This is one of the biggest lessons in my life. I still can't understand — that fight was won. I had it. It was in my hands and I just let him [stay in it] because I saw his injury — and f***, man."

Long considered a dark horse contender at 205 pounds, Ulberg has been on fire since dropping his UFC debut in 2021. He entered his first career title shot riding a nine-fight UFC win streak highlighted by big performances over veteran contenders Dominick Reyes and Volkan Oezdemir, as well as former champ Jan Blachowicz.

Prochazka also walked into UFC 327 on the heels of back-to-back highlight-reel knockouts of Jamahal Hill and Khalil Rountree Jr. in 2025. Widely hailed as one of the most exciting — and eccentric — talents in UFC history, the 33-year-old Czech has still fought to decision just once across his 32 career victories. He claimed the UFC light heavyweight title in 2022 but subsequently dropped it to Alex Pereira, who vacated the belt earlier this year in order to move up to heavyweight.

    • I still cannot believe what I just watched.

    • Unreal. Just unreal stuff from the new champ.

    • That was ABSURD!

    • Fight is on. Ulberg chops to the outside leg to start. Another one lands, as Prochazka bounces as he usually does. Prochazka presses to eat a left hand, then another low kick. Prochazka takes another leg kick. Ulberg is going to that well early and often. Prochazka jabs the body. Prochazka searches for a long pair of punches and Ulberg spins, seemingly tweaking his knee or something odd. Ulberg eats a jab then his knee buckles. Prochazka asks him to trade, and Ulberg obliges! A leg kick to the Ulberg knee staggers him. Something is definitely wrong. Prochazka attacks with another kick. Ulberg goes for a head kick and his leg buckles. Yuck. That was nasty. Prochazka kicks at the leg again, then lands a left hook upstairs. Prochazka pours it on but gets clipped! It's over! Holy s***! He did it on one leg! WHAT.

    • UFC 327's main event is officially underway!

    • If memory serves, I can't say I've ever bet against Procházka — outside of maybe his Pereira rematch.

      And I don't plan to start now.

      The collective MMA world certainly appreciates the glorious madness that Procházka brings, but somehow he still feels underappreciated. When conversations turn to the most entertaining fighters of all time, Procházka is a name that demands inclusion. He's only gone the distance once in 38 appearances. Think about how absurd that is.

      Procházka embodies innovation, uniqueness and awkwardness all at once. Few fighters throughout MMA history, especially at 205 pounds, have moved with the aggressively deceptive patterns of Procházka. But against much sharper technical strikers like Pereira, Procházka's awkwardness hasn't paid off. It could also be problematic against a cannon like Ulberg.

      The rubber will meet the road early in this matchup — Procházka isn't necessarily a slow starter, but we've seen him walk through the fire and fall behind on the judges' scorecards many times. His most recent war with Khalil Rountree Jr. is a prime example — Procházka needed a finish and channeled his inner samurai spirit to march forward like a man possessed in Round 3. Ultimately, he delivered with a relentless flurry of forceful punches that no one has been able to withstand.

      Ulberg will need to force the action early, which would be unlike his typical performances, despite some quick finishes on his record. As the level of competition has increased, so has Ulberg's fight IQ, leading him to more methodical approaches. But against Procházka, he'll want to launch heat-seeking missiles to close the show as quickly as he can. Otherwise, he'll be on his way to suffering the same late fate as many of Procházka's past victims.

      In terms of experience, this fight favors Procházka too. His offense has always been lethal. Defensively, he's tightened previous holes and continually woven in new elements into his movement. As long as the former champion avoids a thumping Ulberg blow in the early rounds, expect to hear "and new" again for the Czech dynamo.

      Pick: Procházka

      10-9 Costa.

    • After arguably his best overall career performance against Roman Koylov last year, Costa has decided to move up in weight to challenge an undefeated contender.

      The Costa saga is an odd one, folks.

      Costa's last appearance in the light heavyweight division was rough and controversial — he was a shell of himself in a 2021 decision loss to Marvin Vettori, especially compared to the force he was in his latest victory over Koylov. The circumstances were bizarre for that fight, as Costa and Vettori were originally booked to fight at 185 pounds — until Costa decided he didn't want to. With proper preparation this time, he should carry over his impressive form from the Koylov win. And he's going to need it.

      Murzakanov had been touted as a questionable prospect with clear talent, but he was unproven due to the level of competition. It wasn't until he stopped perennial contender Aleksandar Rakic in October that the masses realized: Yeah, this dude can crack and he's no joke at light heavyweight.

      Costa has only tasted defeat via strikes once, against Israel Adesanya in his lone UFC title fight. Tactically, Costa has all the tools to out-strike Murzakanov. As powerful as he's always been, Costa has stunningly failed to score a finish since 2018. His durability will be key to keeping him in this fight, but every time he gets touched, he'll be damaged, as Murzakanov consistently seeks the knockout blow. It should be a volume vs. damage affair, leaning in the Russian's favor as he ascends up the division.

      Pick: Murzakanov
