Oleksandr Usyk has surrendered the three remaining heavyweight world title belts he held, a move that reshapes the division’s landscape and leaves a mandatory defence against Agit Kabayel in tatters. In a social media video posted on Friday, the 39-year-old Ukrainian declared he was vacating the WBC, WBA and IBF championships to “make them free so that the guys who are in line for them can box”. He insisted he was not retiring, promising a “last dance”, but gave no indication of an opponent or timeline.

The announcement comes barely a month after Usyk’s controversial 11th-round stoppage of Dutch kickboxer Rico Verhoeven at the Pyramids of Giza. That voluntary defence of the WBC strap saw the champion trailing on the scorecards before a disputed finish rescued his unbeaten record, which now stands at 25 wins with 16 knockouts. It was the latest in a series of belt manoeuvres: Usyk had already vacated the IBF title in 2024 to pursue a lucrative rematch with Tyson Fury, regained it from Daniel Dubois in July 2025, then relinquished the WBO version months later. Viewed from Kyiv, the pattern reflects a career strategy that prioritises legacy and financial reward over mandatory obligations.

The immediate consequence is the collapse of a mandated WBC title fight against Germany’s Kabayel. The sanctioning body had ordered the bout in early June, but Kabayel’s manager, Lasse Krüger, told Bild that Usyk’s camp never engaged in serious negotiations, adding: “It doesn’t look as if Usyk fancies a hard day’s work with Agit in the ring.” WBC president Mauricio Sulaimán had previously stressed the mandatory nature of the contest, and the organisation must now decide whether to elevate interim champion Kabayel to full world champion or order a bout for the vacant belt. Either outcome would give Germany its first heavyweight titlist since Max Schmeling’s reign ended in 1932.

British boxing circles, where Usyk built much of his legend through back-to-back victories over Anthony Joshua, Tyson Fury and Dubois, are absorbing the news with a mix of admiration and uncertainty. The Ukrainian’s dominance over the UK’s premier heavyweights has been a defining thread of the division, and his departure from the title picture removes the gravitational centre around which matchmaking has revolved. Fury has long agitated for a trilogy, but his own plans for a warm-up fight before a long-awaited Joshua clash make that prospect remote.

Speculation over Usyk’s final act is intensifying. Bild reports that he may sign with Zuffa Boxing, the promotional venture of UFC president Dana White, while his manager had earlier hinted at an imminent career announcement. For now, the belts are vacant, the mandatory challenger is waiting, and the sport’s most accomplished active heavyweight has left the championship picture on his own terms, with only a cryptic promise of one more performance to come.
