UFC light heavyweight contender Carlos Ulberg has suffered a torn anterior cruciate ligament (ACL), according to his manager Ash Belcastro. Belcastro confirmed that Ulberg's surgery went "very well" and that the fighter is focused on returning as quickly as possible. However, the recovery timeline for an ACL tear typically extends up to 12 months, meaning Ulberg may not compete again until late 2026 at the earliest. The injury raises questions about whether the UFC should introduce an interim title in the light heavyweight division during his absence. Ulberg was recently competing at a high level in the division before sustaining this significant injury.
Carlos Ulberg has suffered a torn ACL and faces a recovery period of up to 12 months, his manager Ash Belcastro confirmed on April 17, 2026, meaning the New Zealander could be sidelined until late 2026 at the earliest.
Ulberg, known as "Black Jag," enters this layoff as one of the most dangerous fighters in the UFC light heavyweight division. The City Kickboxing product holds an impressive record of 15 wins and just one loss, and at 35 years old he sits ranked third in the division. Standing six-foot-four with a 77-inch reach, the orthodox striker has posted a remarkable 6.54 significant strikes landed per minute alongside a 55 percent striking accuracy — numbers that reflect his reputation as a high-volume, precise finisher on the feet.

Belcastro offered some measured optimism, confirming that Ulberg's surgery went very well and that the fighter is already focused on returning as quickly as possible. ACL recoveries are notoriously demanding, however, and a 12-month timeline is considered standard for combat sport athletes.
Why it matters
- Ulberg's absence removes the division's third-ranked contender from competition for the foreseeable future, disrupting the light heavyweight title picture.
- The extended layoff has prompted discussion about whether the UFC should install an interim light heavyweight champion while Ulberg is sidelined.
- His combination of elite striking volume and a tall, rangy frame made him a genuine threat at the top of the division, and that style matchup will be missed in upcoming title conversations.
