In a seismic shift that reverberated across the heavyweight division, Oleksandr Usyk stunned the boxing world on Monday evening by formally relinquishing his WBO heavyweight championship.
The Ukrainian maestro’s decision brought a swift end to his second stint as undisputed king of the division—a remarkable era that peaked just four months earlier with a brutal fifth-round knockout of Daniel Dubois at Wembley Stadium’s BoxPark venue.
Usyk, 38 and still undefeated at 24-0 with 15 knockouts, had entered that July 19 showdown already clutching the WBA (Super), WBC, and WBO belts, earned through a storied path of triumphs including back-to-back victories over Tyson Fury in 2024 and December 2024.
The emphatic stoppage of Dubois—delivered via a savage left hook that left the Briton sprawled on the canvas—netted Usyk the IBF strap, crowning him the first fighter in the four-belt era to achieve undisputed status at both cruiserweight and heavyweight.
It was a historic nod to his unparalleled footwork, ring IQ, and resilience, qualities that have defined a career spanning Olympic gold in 2012 and an undisputed cruiserweight reign in 2018.
Yet, glory in boxing is fleeting, bound by the ironclad rules of sanctioning bodies and mandatory challengers.
Usyk’s team cited a combination of factors for the vacancy: a lingering back injury that had already postponed an earlier defense against Joseph Parker, and a strategic pivot toward high-profile bouts in 2026, potentially including a trilogy with Fury or a clash with emerging threats like Anthony Joshua.
“This is not a farewell, but—as expressed by his team—a respectful pause,” read the WBO’s official statement, signed by president Gustavo Olivieri. The organization lavished praise on Usyk as “a champion of champions,” hailing his embodiment of “excellence, discipline, integrity, and patriotism” amid Ukraine’s ongoing struggles.
The ripple effects were immediate and profound. Within hours of the WBO’s announcement, Fabio Wardley—the towering 30-year-old from Ipswich, England—was elevated from interim champion to full-fledged WBO heavyweight titleholder, bypassing the need for a grueling title fight.
Wardley (20-0-1, 19 KOs), a 6’5″ southpaw with a sledgehammer right hand, had stormed into contention last month with a controversial 11th-round TKO of former WBO and WBA champion Joseph Parker at London’s O2 Arena on October 25.
Usyk’s vacancy strips him of undisputed glory once more—this marks the third time he’s surrendered belts outside the ring, following cruiserweight unification in 2018 and an IBF relinquishment before his Fury rematch.
