Carlos Ulberg's manager Ash Belcastro has confirmed that the fighter suffered a torn anterior cruciate ligament (ACL). Belcastro stated that Ulberg's surgery went "very well" and that the fighter is focused on returning as soon as possible. Recovery from this type of injury can take up to 12 months, and it is uncertain whether Ulberg will be able to compete by the end of 2026. The post raises the question of whether an interim title should be introduced during his absence. This is a significant injury setback for the light heavyweight contender.
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 cast doubt over any return to competition before the end of 2026.
Belcastro reported that the procedure went "very well" and that Ulberg is already focused on getting back to the octagon as quickly as possible. Still, the nature of an ACL injury means the New Zealander faces an extended spell on the sidelines at a pivotal moment in his career.
Ulberg, nicknamed "Black Jag," enters his rehabilitation as the number-three ranked light heavyweight contender in the world. The 35-year-old City Kickboxing product carries a 15-1 record and is one of the division's most dangerous strikers, landing 6.54 significant strikes per minute at a 55 percent accuracy rate. Standing six-foot-four with a 77-inch reach, he presents a difficult physical puzzle for any opponent at 205 pounds.
Why it matters
- Ulberg's absence removes the division's third-ranked contender from competition for the foreseeable future, disrupting the light heavyweight title picture.
- A recovery lasting up to 12 months raises the question of whether the promotion should consider an interim championship to keep the division active in his absence.
- The injury sidelines one of the sport's most prolific volume strikers at what should be the peak of his contendership run.
