Carlos Ulberg's manager Ash Belcastro has confirmed that the light heavyweight fighter suffered a torn anterior cruciate ligament (ACL). Belcastro reported that Ulberg's surgery went "very well" and that the fighter is focused on returning as quickly as possible. However, recovery from an ACL tear typically takes up to 12 months, which could keep Ulberg out of action for the remainder of 2026. The injury raises questions about whether the UFC should introduce an interim title in the division during Ulberg's extended absence. The post includes a poll asking fans whether an interim championship is necessary.
Carlos Ulberg has undergone surgery for a torn anterior cruciate ligament, his manager Ash Belcastro confirmed on April 17, putting the New Zealand light heavyweight's 2026 schedule in serious doubt.
Belcastro reported that the procedure went "very well" and that Ulberg is already focused on returning as quickly as possible. However, ACL recoveries typically require up to twelve months, meaning the 35-year-old could miss the rest of the competitive year entirely.

Ulberg, known as "Black Jag," enters this period as the third-ranked light heavyweight in the UFC. Fighting out of City Kickboxing, the six-foot-four orthodox striker carries a 15-1-0 professional record and has established himself as one of the division's most dangerous stand-up threats. He lands 6.54 significant strikes per minute at a 55 percent accuracy rate, numbers that place him among the most efficient volume strikers in the 205-pound class. His reach of 77 inches — 196 cm — gives him a natural edge in that role.
Why it matters
- Ulberg's absence removes the division's third-ranked contender from the picture for potentially a full calendar year
- With a top-three fighter sidelined this long, pressure may grow on the UFC to consider an interim title to keep the division active
- His striking-heavy style had made him a high-profile matchup threat for any fighter near the top of the rankings
- City Kickboxing loses one of its most prominent active competitors during the layoff
