Carlos Ulberg's manager Ash Belcastro confirmed that the light heavyweight contender suffered a torn anterior cruciate ligament. Belcastro stated that the surgery went "very well" and that Ulberg is "focused on returning as soon as possible." Recovery from this type of injury can take up to 12 months, which means Ulberg may not compete again until late 2026. The post raises questions about whether an interim title should be introduced during his absence.
Carlos Ulberg has undergone surgery for a torn anterior cruciate ligament, his manager Ash Belcastro confirmed on April 17, with a recovery timeline that could stretch up to 12 months and sideline the New Zealand contender until late 2026.
Belcastro said the procedure went "very well" and that Ulberg is "focused on returning as soon as possible," but the nature of an ACL repair means the 35-year-old faces a lengthy rehabilitation before he can compete again. The news raises immediate questions about how the light heavyweight division will be managed during his absence, including whether an interim title could be introduced.
Ulberg, who trains out of City Kickboxing in Auckland, holds the number-three ranking at 205 pounds and carries a record of 15 wins and one loss. Standing six-foot-four with a 77-inch reach, the orthodox striker has been one of the more dangerous finishers in the division, landing an impressive 6.54 significant strikes per minute at 55 percent accuracy — numbers that place him among the most prolific volume strikers in the weight class. His grappling output is limited by design, averaging just 0.55 takedowns and 0.2 submission attempts per 15 minutes, reflecting a game built almost entirely around his striking.
Why it matters
- Ulberg's absence removes a top-three contender from the light heavyweight picture for the foreseeable future
- A recovery of up to 12 months could prompt discussion around an interim championship to keep the division active
- His high-volume striking style makes him difficult to replace on short notice with a comparable stylistic matchup for any potential title eliminator
