LONDON — Deontay Wilder fought through a chaotic 12-round war to secure a split decision victory over British heavyweight Derek Chisora on Saturday night at the O2 Arena.

The contest served as a milestone for both veterans, marking the 50th professional fight for each man and the 100th combined in-ring appearance for the pair. Wilder, the former WBC champion, managed to edge out Chisora in a contest described as a “slugfest” that kept the London crowd on their feet for the full 36 minutes of action.

The Scorecards and Key Moments

The officiating in the ring was a point of contention, with referee Mark Bates appearing frequently overwhelmed by the mayhem. The judges’ scorecards reflected the closely contested and messy nature of the brawl:

• Judge 1: 115-113 (Wilder)
• Judge 2: 115-111 (Wilder)
• Judge 3: 115-112 (Chisora)

Wilder’s victory is particularly notable as it represents his first decision win over the full championship distance in over a decade, a feat he had not achieved since his initial world title success against Bermane Stiverne in January 2015.

Round 8: The Turning Point

The most significant sequence of the fight occurred in the eighth round, when Wilder landed his trademark right hand to score a knockdown, delivering the bout’s signature moment in an otherwise thrillingly chaotic encounter.

A Clash of Veterans

Despite the win, the performance highlighted the toll of their long careers. Chisora, fighting at a career-heaviest weight, found success early by targeting Wilder’s body, but struggled to sustain his attacks as the fight progressed.

Wilder, although victorious, appeared to be a shadow of the powerhouse who dominated the division a decade ago. However, the win allowed him to move past recent defeats to Joseph Parker, Zhilei Zhang, and Tyson Fury.

I had an adorable opponent. I knew Derek was going to bring everything he had. In the ring, I saw his temple start to swell. I said, ‘You’ve got to live for your kids.’ Too many lives have been lost in this ring, nobody gives a damn about us. Us fighters have to seem out for each other. Tonight, I looked out for him. I aim for him to live for his kids. It’s time for us to take care of each other. I have seven [kids] of my own, those are my best friends. Kids, I’m coming home. — Deontay Wilder

Retirement and Future Plans

Coming into the bout, Chisora had pledged to retire after his 50th fight. Following the loss, however, the Briton remained noncommittal about his future.

I’m going to go home with the boss lady and see. I’m going to go home and drop the kids, do the school run. — Derek Chisora

While Wilder mentioned the possibility of another pursuit of world honors, analysts suggest he may be better served avoiding further high-risk bouts. Despite the brutality of the fight, both men shared a fond and respectful exchange after the final bell, highlighting a friendship forged in the “brutally dangerous trade” of heavyweight boxing.
