Wardley Urges Chisora to Retire After Wilder Fight at The O2

Three days before Derek Chisora and Deontay Wilder lace up for the 50th fight of their respective careers on the same night, the WBO heavyweight champion has drawn a clear line: Chisora should retire regardless of what happens at The O2 Arena in London on Saturday.

Fabio Wardley, unbeaten at 20-0-1 with 19 knockouts and the current WBO titleholder after Oleksandr Usyk vacated the belt in 2025, made his position clear in a BBC Sport column. His concern is not abstract. Wardley had been in talks to fight either Chisora or Wilder for that same April 4 date before the two veterans chose each other, giving him a closer vantage point than most on what is actually at stake.

The card has been billed as '100' because both fighters are stepping through the ropes for the 50th time on the same night. Chisora, 42, from Finchley via Zimbabwe and carrying a record of 36-13 with 23 knockouts, arrives on a three-fight winning streak, his last bout a unanimous decision over Otto Wallin on 8 February 2025. Deontay Wilder, 39, the former WBC heavyweight champion and still one of the most dangerous punchers the division has produced, brings a record of 44-4-1 and 43 knockouts. Sky Bet make Chisora the 1/2 favourite and Wilder the 13/8 underdog, a remarkable inversion given the American's reputation.

It is Wilder's recent record that most sharpens the welfare argument. He has lost four of his last six fights, including consecutive defeats by Joseph Parker on points in December 2023 and a fifth-round TKO by Zhilei Zhang in June 2024. Chisora's accumulated wear runs deeper still: 13 losses across a career in which he has shared the ring with Tyson Fury, who stopped him in round ten, alongside Oleksandr Usyk, David Haye, Vitali Klitschko and Joseph Parker.

The commercial architecture sustaining these matchups is not separate from the welfare question; it is central to it. The fight is broadcast exclusively on DAZN as a worldwide pay-per-view event, with BBC holding radio rights via a deal with DAZN and Queensberry Promotions. Both men remain commercially viable in ways that younger, less decorated heavyweights are not, and that marketability creates sustained pressure to keep competing that no licensing standard can fully resolve on its own.

The British Boxing Board of Control requires MRI and MRA brain scans upon application for a boxer's licence, with annual MRI scans compulsory for all licensed professionals in Britain. The Association of Boxing Commissions similarly requires fighters aged 38 and over to submit EKG and stress test results with a clearance letter before competing, and those over 40 must provide an MRI of the brain with physician sign-off. Those protocols represent meaningful protections on paper. Whether promoters and sanctioning bodies apply them with consistent rigour when a pay-per-view headliner is on the table is a different matter.

Chisora has made and broken retirement pledges before. He insists this time the decision stands, win or lose. Former world champion Carl Froch has already identified Chisora, Dave Allen and Wardley as compelling future opponents for Wilder, demonstrating how quickly the sport finds reasons to reopen the door for fighters who remain box-office draws.

Wardley defends his WBO title against Daniel Dubois on 9 May 2026 at the Co-op Live Arena in Manchester and has his own interests in heavyweight positioning. But his public call for Chisora to stop is the kind of honest reckoning a sport built on punishment rarely permits itself before the damage is already done.
