A new era at light heavyweight began in the main event of UFC 327 in Miami, with Carlos Ulberg winning the vacant Ultimate Fighting Championship light heavyweight title over former champion Jiri Prochazka.
On Saturday, while United States President Donald Trump sat cageside, Ulberg landed a perfect left hook to Prochazka’s chin and won the undisputed belt with a knockout at the 3:45 mark of the first round.

Ulberg (14-1 MMA, 10-1 UFC) finished Prochazka (32-6-1 MMA, 6-3 UFC) after nearly losing the fight due to a knee injury, catching Prochazka with a left hook followed by strikes to win the title .
“I tore my knee out, but I never counted myself out,” Ulberg said. “I knew I just needed that one shot, and eventually I got it. So I knew Jiri was hesitant to come forward. And as soon as I got my left hand down, he was going.
“It’s about having those moments.”
Ulberg has won 10 in a row, while Prochazka has gone 1-3 in UFC title bouts since June 2022. Two of those losses were to Alex Pereira (13-3).
Ulberg (15-1-0) appeared to be in some trouble early in the first round when he planted his foot and his right knee bent awkwardly. Prochazka (32-6-1) immediately went to work on Ulberg’s left leg, and instead of attacking aggressively to finish it off, kicked repeatedly in hopes of taking both legs away.
“I felt sorry for him and that’s the biggest lesson of my life,” Prochazka said. “That battle was won, she was with me, she was in my hands. I saw her hurt, and… I’ll be back. That’s what life is about, learn and get better.”
The matchup was created after former champion Alex Pereira vacated the belt to step up and challenge for the interim heavyweight crown at UFC Freedom 250 on Trump’s 80th birthday on June 14 at the White House.
Earlier, while on his way to the field, Trump’s Truth social account posted an advertisement for the event.
Trump entered the Cascia Center accompanied by UFC President Dana White and several members of the Trump family.
As a Kid Rock song started playing from the speakers, Trump walked to his seat, where Secretary of State Marco Rubio was waiting. US Ambassador to India Sergio Gore was also present nearby.

Earlier, Paulo Costa rallied to stop Azamat Murzakanov’s undefeated record in the third round. Costa (16-4) has won his last two fights as he fights primarily at middleweight. Murzakanov (16-1) has won five of his first seven fights in the UFC through 2022 by KO/TKO.
In the co-main event, Azamat Murzakanov (17-0-0) used a roundhouse right to the head to drop Paulo Costa (15-5-0) and end the bout at the 1:23 mark of the third round.
After the victory, Murzakanov climbed onto the Octagon apron to shake Trump’s hand and was praised by the President. Murzakanov acknowledged Trump during a post-fight interview with Rogan.
Josh Hockitt (9-0-0) and Curtis Blaydes (19-6-0) defeated each other in the Clash of the Night, with Trump excitedly watching the veterans and fans yelling “This is amazing!” While the fighters left each other’s faces bloody. Hockit won via unanimous decision (29–28, 29–28, 29–28).

Lewis vs. Hockit added to White House fight card
Following Hockitt’s win, White revealed on social media that a match between Hockitt and Derrick Lewis had been added to UFC Freedom 250. According to White’s video, Trump asked why Lewis was not on the White House card.
The UFC chief said he called Lewis and offered him the fight, and when Rogan jokingly asked during the broadcast if there was room for Hokitika on the card, the match came together.
“President Trump created half of that fight, Rogan created the other half,” White said in the video. “Both guys have agreed and accepted the fight.”
