Carlos Ulberg's manager Ash Belcastro has confirmed that the light heavyweight fighter suffered a torn ACL (anterior cruciate ligament). Ulberg has already undergone surgery, which according to his manager went "very well." Belcastro stated that Ulberg is focused on returning to competition as quickly as possible. Recovery from ACL surgery typically takes up to 12 months, meaning Ulberg may not return to the octagon until late 2026 at the earliest. The extended absence raises questions about whether a interim title should be introduced in the division.
Carlos Ulberg has suffered a torn ACL and has already undergone surgery, his manager Ash Belcastro confirmed on April 17, sidelining the third-ranked light heavyweight contender for what could be the remainder of 2026.
Ulberg, known as "Black Jag," carries a 15-1 record and has established himself as one of the most dangerous strikers in the 205-pound division. The 35-year-old New Zealander, who trains out of City Kickboxing, stands six-foot-four with a 77-inch reach and lands an impressive 6.54 significant strikes per minute at a 55 percent accuracy rate — numbers that place him among the most efficient and prolific strikers in the weight class. Belcastro noted the surgery went "very well" and that Ulberg is determined to return to competition as soon as possible.
Standard ACL recovery timelines stretch up to 12 months, meaning the earliest realistic return window would be late 2026 at the soonest.
Why it matters
- Ulberg's absence removes the division's number-three contender from the title picture for an extended period.
- With a top-ranked fighter unavailable for potentially the rest of the year, the light heavyweight title picture faces significant disruption.
- The prolonged vacancy in the contender queue has already prompted discussion around whether the division may need an interim title to keep the 205-pound picture active.
- Ulberg's striking-heavy style and high output made him one of the most anticipated challengers in the weight class, and his absence leaves a notable gap in the rankings.
