In the main event of UFC 327 on April 11, 2026, Carlos Ulberg scored a stunning knockout victory over Jiri Prochazka to claim the vacant UFC Light Heavyweight Championship. Despite suffering a serious knee injury early in the first round that left him hobbled, Ulberg remained composed and landed a perfectly timed left hook to knock out Prochazka at 3:45 of the opening round.

Why it matters

Ulberg's victory was unexpected given the severity of his knee injury, which could potentially sideline him for an extended period. The fight's dramatic ending has sparked speculation about the introduction of an interim light heavyweight title if Ulberg is unable to defend the belt in the near future.

The details

As the fight began, Ulberg's right knee buckled, leaving him with a serious injury that slowed his movement. Prochazka pressed his advantage, low-kicking Ulberg's wounded leg. However, Ulberg remained composed, waiting for his opportunity. When Prochazka came forward, Ulberg planted his weight and landed a clean left hook that knocked Prochazka to the canvas, ending the fight.
