Carlos Ulberg's manager Ash Belcastro has confirmed that the light heavyweight contender suffered a torn anterior cruciate ligament (ACL). The manager reported that Ulberg's surgery went "very well" and the fighter is focused on returning as quickly as possible. However, recovery from an ACL tear typically requires up to 12 months of rehabilitation. There is uncertainty whether Ulberg will be able to compete in the octagon by the end of 2026. The injury raises questions about whether the UFC should introduce an interim title in the light heavyweight division during his extended absence.
Carlos Ulberg has suffered a torn anterior cruciate ligament, his manager Ash Belcastro confirmed on April 17, 2026, casting serious doubt over the New Zealand light heavyweight contender's ability to compete before the end of next year.
Belcastro reported that Ulberg's surgery went very well and that the fighter is determined to return as quickly as possible. Despite that encouraging update, ACL rehabilitation typically demands up to 12 months, meaning the 35-year-old City Kickboxing product faces a lengthy road back to the octagon.
Ulberg currently sits third in the light heavyweight rankings with a record of 15 wins and one loss. Standing six-foot-four with a 77-inch reach, the orthodox striker has built his reputation on relentless output, landing 6.54 significant strikes per minute at a 55 percent accuracy rate — numbers that place him among the division's most dangerous stand-up fighters.
Why it matters
- Ulberg's absence could stretch well into 2027, removing the third-ranked contender from the divisional picture for an extended period.
- The extended timeline puts pressure on the UFC to consider how the light heavyweight title picture moves forward, with some questioning whether an interim championship may be necessary.
- His attacking striking style and elite-level team at City Kickboxing made him one of the most anticipated challengers at 205 pounds; that matchmaking calculus now has to be recalculated entirely.
