Ulberg describes knee injury after Prochazka fight: 'unbearable pain'

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 the pain mid-fight as "unbearable" and his knee as barely functional in the days that followed.

The New Zealand light heavyweight, who fights out of City Kickboxing, improved his record to 15-1-0 with the win. Ranked third in the division at 35 years old, Ulberg stands six-foot-four with a 77-inch reach and has built a reputation as one of the more dangerous strikers in the weight class, landing 6.54 significant strikes per minute at 55 percent accuracy. He disclosed that during the bout his knee felt as though it was repeatedly slipping in and out of the joint, leaving him unable to bear weight on it. After the fight, the knee was badly swollen and he could only move with great difficulty. No specific diagnosis or recovery timeline has been made public.

His opponent, Jiri Prochazka of the Czech Republic, entered the contest ranked second at light heavyweight with a record of 32-6-1. The 33-year-old trains out of Jetsaam Gym Brno and is among the most aggressive strikers in MMA, averaging 5.69 significant strikes per minute at 55 percent accuracy. Standing six-foot-three with an 80-inch reach, Prochazka presented Ulberg with a considerable physical and technical challenge.

Why it matters

• Ulberg's win over the second-ranked Prochazka strengthens his case for a light heavyweight title shot, but the knee injury clouds his near-term availability.
• The severity of the injury, as Ulberg described it, suggests a potential structural issue that could require significant time away from competition.
• A prolonged absence would affect the shape of the light heavyweight top five at a moment when the division's title picture is in flux.
