Carlos Ulberg loses championship belt after victory celebration

Carlos Ulberg has revealed he misplaced his light heavyweight championship belt in the aftermath of his post-fight victory celebrations, admitting he is not entirely sure where it ended up.

The New Zealand fighter, who competes out of City Kickboxing, explained that he chose not to carry the belt around with him following the party and left it at an apartment. Ulberg suspects the title is still there, joking that one of his friends is likely sleeping with it.

Ulberg, nicknamed "Black Jag," carries a record of 15 wins and one loss in the light heavyweight division, where he currently sits ranked third. The 35-year-old stands six-foot-four with a 77-inch reach and has built his reputation on a striking-heavy style, landing 6.54 significant strikes per minute at an accuracy rate of 55 percent — numbers that rank among the more prolific outputs in the division.

Why it matters

• Ulberg is now a light heavyweight champion, marking a major milestone for City Kickboxing's storied roster
• His relaxed demeanor off camera reinforces the laid-back public persona he has projected throughout his rise up the rankings
• The belt's temporary disappearance is unlikely to cause any real concern, but it adds a lighthearted footnote to what is otherwise a landmark moment in his career

Despite the uncertainty around the belt's exact location, Ulberg appeared entirely unbothered by the situation, treating it as an amusing detail from what was clearly an enthusiastic celebration. It is a rare light moment in a sport that seldom produces them.
