Carlos Ulberg has gone under the knife, with the New Zealand light heavyweight announcing via social media that he has successfully undergone knee surgery.
Ulberg, who fights out of City Kickboxing, offered no details on how the injury occurred or when he expects to return to the octagon. The announcement drew well-wishes from fans and the combat sports community, though a recovery timeline remains unknown.

The 35-year-old is one of the most dangerous strikers in the 205-pound division. Known as "Black Jag," Ulberg carries a 15-1 professional record and currently sits ranked third in the UFC light heavyweight rankings. Standing six-foot-four with a 77-inch reach, he presents a difficult physical puzzle for any opponent, and his output reflects his aggressive style — he lands 6.54 significant strikes per minute at a striking accuracy of 55 percent.
Why it matters
- Ulberg's third-place ranking means any extended absence could affect his position in a crowded and active light heavyweight title picture.
- His striking-heavy game, built on volume and accuracy, may require a full recovery before he can return to peak form.
- City Kickboxing will be managing his rehabilitation, keeping one of the division's top contenders temporarily on the sidelines.
