In Miami, Carlos Ulberg captured the vacant light‑heavyweight belt at UFC 327, knocking out Jiri Prochazka with a left hook in the opening round. The New Zealander win came despite a right‑knee injury that forced him to stumble repeatedly before the decisive strike, and it puts him on a lucrative title‑defense schedule.

Prochazka, the 33‑year‑old former champion, appeared to have the fight in hand before dropping his guard after sensing Ulberg’s injury, later saying he felt “mercy” for his opponent. The bout was set after Alex Pereira vacated the title to move up to heavyweight, leaving the second‑ranked Prochazka to face third‑ranked Ulberg, who earned his shot by KO‑ing Dominick Reyes in September earlier this season.

Dana White and commentator Daniel Cormier speculated the damage could be an ACL tear, an injury that typically sidelines fighters for nine months or more. President Donald Trump watched from the octagon side, underscoring the event’s high profile. Ulberg now faces a recovery battle, but his knockout crowns him the division’s new champion.
