Chisora’s Dubois Title Route Gave Way to Heavyweight
Derek Chisora’s victory over Otto Wallin in February 2025 positioned him as the IBF mandatory challenger to heavyweight champion Daniel Dubois. The designation raised the possibility of a major championship opportunity, but the projected Chisora–Dubois fight never took place.
The mandatory position created an opening
In March, the IBF confirmed that Chisora was its mandatory challenger and said the defense was due to be ordered on April 22. His unanimous-decision win against Wallin had been the forty-ninth fight of his professional career.
The governing body explained that there was insufficient time for another eliminator before Dubois’s mandatory obligation fell due. Chisora’s position therefore offered a direct route toward a title challenge on paper.
Unification took priority over the defense
The same IBF response made clear that a unification contest would take precedence. Dubois was pursuing a rematch with Oleksandr Usyk, whose other heavyweight belts made an undisputed championship fight possible.
That meeting ultimately took place at Wembley Stadium on July 19, 2025. Usyk knocked out Dubois in the fifth round, reclaiming the IBF title alongside the other major heavyweight championships.
Chisora’s next major bout went elsewhere
Chisora later faced Deontay Wilder at London’s O2 Arena on April 4, 2026. Wilder won a split decision after twelve rounds.
The sequence illustrates the distinction between holding a mandatory position and completing a championship bout. Chisora had a recognized claim in the IBF order, but Dubois’s unification fight changed the title picture before their proposed meeting could become a finished contest.
