Carlos Ulberg reveals severe knee injury from UFC 327 bout

Carlos Ulberg has revealed the extent of a serious knee injury he sustained during his victory over Jiri Prochazka at UFC 327 on April 11, describing pain severe enough to leave him barely able to stand in the aftermath of the fight.

The New Zealand light heavyweight, who trains out of City Kickboxing, disclosed that his knee was heavily swollen and that he experienced a disturbing sensation during the bout of the joint moving in and out of the socket. The pain was at points unbearable, preventing him from putting any weight on the leg. Despite fighting through those conditions, Ulberg secured the win.

Ranked third in the light heavyweight division, Ulberg improved his professional record to 15-1-0 with the performance. The 35-year-old stands six-foot-four with a 77-inch reach and has built a reputation as one of the more active strikers in the division, averaging 6.54 significant strikes landed per minute at a striking accuracy of 55 percent. The victory over Prochazka represents arguably the most significant scalp of his career to date.

Why it matters

• A knee injury of this severity raises immediate questions about Ulberg's timeline before his next appearance inside the octagon.
• Sitting third in the light heavyweight rankings, Ulberg was positioning himself as a title contender, and any extended absence could affect that standing.
• The manner in which he gutted out the victory — fighting through what he described as a potentially dislocating knee — adds significant weight to his case as an elite-level competitor in the division.
