Carlos Ulberg has gone under the knife, announcing via social media that he successfully underwent knee surgery and has begun the rehabilitation process. The New Zealand light heavyweight offered no specifics on the severity of the injury or how long he expects to be sidelined.
Ulberg, nicknamed "Black Jag" and representing the renowned City Kickboxing gym in Auckland, enters this recovery period as one of the division's most dangerous strikers. Ranked third at light heavyweight at 35 years old, he carries a 15-1 record and brings considerable physical tools to the octagon — standing six-foot-four at 193 cm with a 77-inch reach. His offensive output is among the highest in the division, averaging 6.54 significant strikes landed per minute at a 55 percent striking accuracy rate, numbers that reflect the pressure-heavy style he has developed under the City Kickboxing system.

Why it matters
- Ulberg sits third in the light heavyweight rankings, meaning an extended absence could affect his positioning in a competitive title picture
- His elite striking volume and accuracy made him a prime contender; the knee surgery raises questions about when he can return to active competition
- City Kickboxing will oversee his rehabilitation, giving him access to a high-performance environment, though no timeline has been set
No details about when the injury occurred or what specific procedure was performed have been made public. The full scope of his recovery remains unknown as Ulberg focuses on the early stages of rehabilitation.
