Oleksandr Usyk (25-0, 16 KOs) vacated the WBA, WBC and IBF heavyweight titles, ending one of the greatest championships in heavyweight history. The undefeated Ukrainian leaves the division without a unified champion, while it remains unclear if he has fought for the last time.
The move follows Usyk’s decision last year to relinquish the WBO title rather than complete a mandatory defence, a move which saw Fabio Wardley elevated to full champion, who then lost his title to Daniel Dubois. With the WBA, WBC and IBF belts also surrendered, the heavyweight championship will now be contested through the sanctioning bodies’ vacant title procedures.
Few fighters have matched what Usyk has accomplished across two weight classes.
After winning Olympic gold in 2012, Usyk cleaned up the cruiserweight division and became the undisputed champion by defeating Marco Huck, Mairis Briedis, Murat Gassiev and Tony Bellew. Rather than stay there, he moved up to heavyweight and repeated the feat against naturally bigger men, defeating Anthony Joshua twice, Tyson Fury twice and Daniel Dubois while becoming the first undisputed heavyweight champion of the four-belt era. He leaves both divisions having beaten every elite fighter placed before him.
His departure immediately changes the heavyweight title picture.
The WBC has ordered a mandatory defense against interim champion Agit Kabayel, while the WBA and IBF are also nearing mandatory title situations. Instead, each organization must now determine its next champion, opening the door for a new generation of heavyweight title challengers.
Whether Usyk has retired remains unclear.
Retirement has been discussed publicly by members of his team in recent weeks, but the former undisputed champion has not confirmed that he has fought his last fight. He is also connected to exhibition competitions and other events outside the traditional championship scene.
Whatever decision comes next, Usyk’s legacy is secure. He leaves the sport as an undefeated heavyweight champion, an undisputed champion in two divisions, an Olympic gold medalist and one of the most complete fighters of his generation. Few champions have climbed through the sport with so little left to prove.
It’s a conscious decision, which I’m sure will open up new opportunities for me. This is not the end of the story. Continuation forward.
