“Own It Like a Man!” — Derek Chisora doesn’t hold back, blasting Daniel Dubois after his crushing defeat to Oleksandr Usyk.

In the unforgiving world of heavyweight boxing, defeat can either become a stepping stone to greatness or a shadow that follows a fighter throughout his career. For Daniel Dubois, his latest loss to Oleksandr Usyk has ignited more than disappointment—it has sparked a fiery critique from fellow British heavyweight Derek Chisora, who has accused the young fighter of making excuses instead of owning up to failure.

The controversy stems from Dubois’ rematch with Usyk, where he suffered a crushing knockout in the fifth round. For many fans, the fight revived memories of Dubois’ earlier struggles against Joe Joyce, when questions were raised about his resilience under pressure. While Dubois tried to explain the defeat by pointing to refereeing decisions and possible low blows, Chisora was having none of it.

Speaking in an interview, Chisora cut straight to the point: “Own it like a man! He quit again. Stop blaming referees, stop blaming anything else—just own it.” For Chisora, known for his bluntness and warrior spirit, Dubois’ response to defeat represented everything a fighter should avoid: denial, excuses, and deflection.

Chisora went further, contrasting Dubois’ post-fight narrative with the mentality required to survive in boxing’s brutal landscape. “When you lose, you stand there and admit it. You take it on the chin, and you come back stronger. But every time, he’s got an excuse. That’s not what a fighter does.”

The remarks hit hard because they came from a man who has built his career not on an unblemished record, but on grit and refusal to bow out quietly. Derek Chisora has faced—and lost to—some of the sport’s biggest names, yet his reputation remains intact precisely because he never hid from his shortcomings. In fact, his ability to get back up, dust himself off, and keep fighting has made him a fan favorite.

By comparison, Dubois finds himself walking a thin line. At just 27 years old, he still has time to rebuild. He has shown flashes of brilliance, carrying knockout power and size that make him a dangerous opponent in any ring. Yet the lingering perception, reinforced by Chisora’s words, is that he lacks the mental steel that separates contenders from champions.

Public reaction has been divided. Some fans agree with Chisora, applauding his honesty and echoing his call for Dubois to “man up” and accept his defeats without pointing fingers. Others, however, argue that Dubois deserves more compassion—that a young fighter under immense pressure may stumble, and that dismissing him outright risks cutting short a career with real potential.

What cannot be denied is the passion with which Chisora delivered his critique. In a sport where reputations are made as much by attitude as by results, his words carry weight. “No excuses,” he said bluntly. “That’s how real fighters live.”

For Dubois, the path forward now depends less on his physical abilities and more on his response to this challenge. Will he absorb the sting of Chisora’s truth and return stronger, or will the cloud of “excuses” continue to haunt him?

In heavyweight boxing, pride is as valuable as power. And as Derek Chisora reminded the world, there is no shortcut to respect—you have to own it.
