Reports emerged this week that Carlos Ulberg knocked out Jiri Prochazka in the main event of UFC 327 in Miami on April 11 to claim the light heavyweight title, only for the belt to be stripped from him within hours of the victory under circumstances that remain unclear.
Ulberg, nicknamed "Black Jag," entered the fight ranked third in the light heavyweight division and delivered the finish despite reportedly carrying an injured right knee throughout the bout. The 35-year-old New Zealander trains out of City Kickboxing and carries a record of 15 wins and one loss. Standing six-foot-four at 193 cm with a 77-inch reach, he is one of the more physically imposing strikers in the division, averaging 6.54 significant strikes per minute at 55 percent accuracy.
Prochazka, the second-ranked light heavyweight, came in with a record of 32-6-1 and remains one of the most dangerous finishers in the sport. The Czech fighter, who stands six-foot-three with an extraordinary 80-inch reach, averages 5.69 significant strikes landed per minute at the same 55 percent accuracy mark. At 33 years old and representing Jetsaam Gym Brno, he had been viewed as a significant threat heading into the contest at Kaseya Center.
It should be noted that this story is not yet officially confirmed, and key details surrounding the title loss remain unverified at this stage.
Why it matters
- Ulberg's reported title win and near-immediate strip leaves the light heavyweight division without a recognized champion
- Prochazka, ranked second, would be a logical candidate for any rematch or interim title fight
- The division has experienced frequent title changes in recent years, and this development continues that pattern
- The full context behind the stripping — whether administrative, medical, or otherwise — could significantly shape what comes next for both fighters
