Manager Ash Belcastro confirmed that Carlos Ulberg suffered a torn anterior cruciate ligament (ACL). The surgery went very well according to the manager, and Ulberg is focused on returning as soon as possible. However, recovery from an ACL tear can take up to 12 months, and it is uncertain whether Ulberg will be able to compete by the end of 2026. The injury raises questions about whether the UFC should introduce an interim title in the light heavyweight division.
Carlos Ulberg has undergone surgery for a torn anterior cruciate ligament, his manager Ash Belcastro confirmed on April 17, with a recovery timeline that could stretch to 12 months and cast serious doubt over any return to competition before the end of 2026.
Belcastro reported that the procedure went well and that Ulberg remains focused on getting back inside the octagon as soon as possible. However, ACL rehabilitation is a notoriously lengthy process, and a full year on the sideline would represent a significant interruption to one of the light heavyweight division's most compelling careers.
Ulberg, nicknamed "Black Jag," enters this layoff as the third-ranked light heavyweight in the UFC. The 35-year-old New Zealander, who trains out of City Kickboxing in Auckland, carries a 15-1 record and has established himself as one of the most dangerous strikers in the division. Standing six-foot-four with a 77-inch reach, he lands an exceptional 6.54 significant strikes per minute at 55 percent accuracy, numbers that place him among the elite finishers at 205 pounds.
Why it matters
- Ulberg's absence removes the third-ranked contender from the light heavyweight picture for the foreseeable future.
- A 12-month recovery window extends well into late 2026, leaving his next bout date highly uncertain.
- With a top-three contender sidelined, the UFC may face mounting pressure to consider an interim light heavyweight title to keep the division active.
- The injury disrupts what had been a sharp upward trajectory for one of New Zealand combat sports' most prominent figures.
