Manager Ash Belcastro confirmed that Carlos Ulberg has suffered a torn anterior cruciate ligament. Belcastro stated that the surgery went "very well" and Ulberg is "aiming to return as soon as possible." However, the recovery process could take up to 12 months, making it uncertain whether Ulberg will be able to compete in the octagon by the end of 2026. The injury has sparked discussion about whether an interim title should be introduced in his division.
Carlos Ulberg has suffered a torn anterior cruciate ligament, his manager Ash Belcastro confirmed, raising serious doubts about the New Zealand light heavyweight contender's availability for the remainder of 2026.
Belcastro revealed that Ulberg has already undergone surgery, which went "very well," and that the fighter is "aiming to return as soon as possible." Despite that encouraging early report, ACL recoveries of this nature can take up to 12 months, placing any octagon return deep into 2026 at the earliest — or potentially beyond.
Ulberg, known as "Black Jag," carries an impressive 15-1 record and currently sits third in the light heavyweight divisional rankings. The 35-year-old City Kickboxing product stands six-foot-four with a 77-inch reach and has established himself as one of the division's most dangerous strikers, landing 6.54 significant strikes per minute at a 55 percent accuracy rate. That combination of size, volume, and precision had made him a compelling title contender heading into this year.
The injury has already prompted discussion within the sport about whether the light heavyweight division may need an interim title to keep the championship picture active during Ulberg's absence.
Why it matters
- Ulberg's absence removes the division's third-ranked contender from the title picture for a potentially extended period
- A 12-month recovery timeline makes a 2026 return uncertain and could significantly disrupt his momentum
- The interim title conversation suggests the light heavyweight landscape may be reshuffled before Ulberg is cleared to compete again
- His return to full fitness will be closely monitored given the physical demands his striking-heavy style places on his frame
