Carlos Ulberg's manager Ash Belcastro confirmed that the fighter suffered a torn ACL. Belcastro noted that the surgery went very well and Ulberg is aiming to return as soon as possible. However, recovery from such an injury can take up to 12 months, making it uncertain whether Ulberg will compete in the octagon by the end of 2026. The injury raises questions about whether an interim title should be introduced in his division. Ulberg's status as a top contender makes his extended absence significant for the division.
Carlos Ulberg's manager Ash Belcastro has confirmed that the New Zealand light heavyweight suffered a torn ACL, with surgery now complete and a recovery window of up to 12 months casting serious doubt over his ability to compete before the end of 2026.
Ulberg, 35, enters this setback as one of the most dangerous contenders in the 205-pound division. Fighting out of City Kickboxing, the six-foot-four orthodox striker holds a 15-1 record and currently sits ranked third in the light heavyweight rankings. His physical tools are formidable — a 77-inch reach and some of the most prolific striking output in the division, landing 6.54 significant strikes per minute at a 55 percent accuracy rate. Belcastro indicated the surgery went well and that Ulberg is focused on returning as soon as his recovery allows.
Why it matters
- Ulberg's third-ranked status means the light heavyweight title picture loses one of its most credible challengers for the foreseeable future.
- A 12-month recovery timeline could sideline him well into late 2026 or beyond, creating a prolonged gap in divisional activity at the top.
- His absence adds weight to discussions around whether an interim title may be warranted in the light heavyweight division.
- The injury removes a high-volume striker whose output and accuracy had made him a genuine threat to any champion or top-five opponent.
