Carlos Ulberg's manager Ash Belcastro has confirmed that the fighter suffered a torn anterior cruciate ligament (ACL). The manager stated that the surgery went "very well" and that Ulberg is "focused on returning as soon as possible." Recovery from an ACL tear typically takes up to 12 months, casting doubt on whether Ulberg will compete again in 2026. The post includes a poll asking fans whether an interim title should be introduced during his absence. This injury represents a significant setback for Ulberg's career momentum.
Carlos Ulberg has undergone surgery to repair a torn anterior cruciate ligament, his manager Ash Belcastro confirmed on April 17, with a recovery timeline of up to 12 months putting the remainder of 2026 in serious doubt for the New Zealand contender.
Ulberg, 35, enters this setback as one of the most dangerous fighters in the light heavyweight division. Ranked third at 205 pounds and fighting out of City Kickboxing, the six-foot-four orthodox striker carries a 15-1 professional record and has built his reputation on elite stand-up output. His numbers are striking in every sense: he lands 6.54 significant strikes per minute at an accuracy rate of 55 percent, making him one of the more prolific and precise finishers in the division. With a 77-inch reach and 193 cm of frame, he presents a difficult puzzle for any opponent. Belcastro described the procedure as having gone very well and said Ulberg is focused on returning as soon as possible.
Why it matters
- Ulberg's absence removes the division's third-ranked contender from the title picture for potentially all of 2026
- The timing raises questions about how the light heavyweight title scene will be managed, with Belcastro's camp publicly raising the possibility of an interim championship
- His City Kickboxing team has produced elite-level strikers, and the division loses one of its most active finishers while he rehabilitates
- At 35, a 12-month layoff is a meaningful portion of a fighter's competitive window at the top level
