Carlos Ulberg's manager Ash Belcastro has confirmed the fighter suffered a torn anterior cruciate ligament (ACL). Belcastro stated the surgery went "very well" and Ulberg is focused on returning as soon as possible. Recovery from an ACL tear can take up to 12 months, meaning Ulberg may not compete in the octagon until late 2026 at the earliest. The post raises the question of whether an interim title should be introduced during his absence. This injury will sideline the light heavyweight contender for a significant period.
Carlos Ulberg has suffered a torn anterior cruciate ligament and faces a recovery period of up to 12 months, his manager Ash Belcastro confirmed on April 17, 2026.
Belcastro said the surgery went "very well" and that Ulberg is focused on returning as quickly as possible. A standard ACL recovery timeline, however, means the New Zealand light heavyweight is unlikely to set foot in the octagon again until late 2026 at the earliest.
Ulberg, 35, holds a 15-1 record and is ranked third in the UFC light heavyweight division. Fighting out of City Kickboxing, the six-foot-four, 193-centimeter orthodox striker carries a 77-inch reach and has built his reputation on elite stand-up output. He lands 6.54 significant strikes per minute at a striking accuracy of 55 percent — numbers that place him among the more dangerous hands in the division.
Why it matters
- Ulberg is ranked third at light heavyweight, and his absence creates a significant gap in the division's contender landscape.
- A recovery stretching into late 2026 could prompt discussions around an interim title, a question Belcastro's statement already raises.
- With Ulberg's game built almost entirely on striking volume and accuracy, a full and healthy return from knee surgery will be critical to preserving his competitive edge.
