Anthony Joshua faces career-defining moment as Daniel Dubois threatens to end his comeback

Anthony Joshua’s comeback trail faces its toughest test yet as Daniel Dubois threatens to end his return with a single punch.

Daniel Dubois, the undefeated heavyweight contender, has thrown down the gauntlet to Anthony Joshua ahead of their scheduled clash. Dubois warned he will **‘end Joshua’s comeback for good’** in their bout set for 20 September 2026 in London. The 28-year-old Dubois, ranked among the division’s most fearsome punchers, framed the fight as a career-defining moment for Joshua, the 33-year-old former world champion.

Joshua, who last fought in April 2026, has spent 15 months rebuilding his reputation after back-to-back losses to Oleksandr Usyk. His team confirmed negotiations are finalised for the September showdown, with Dubois’ camp pushing for a high-stakes, high-paying spectacle. The purse split remains under wraps, but insiders expect a six-figure minimum for both men.

For Joshua, this isn’t just another fight. A loss to Dubois would likely bury his hopes of regaining a heavyweight title shot. Dubois, 28, holds a 19-1 record with 18 knockouts, while Joshua stands at 26-3. The British public’s patience is wearing thin after two defeats to Usyk, and another setback could force Joshua into early retirement talks.

But a win? That could reignite his title ambitions. Joshua’s team insist he’s sharper than ever, citing a gruelling 12-week camp in Las Vegas. His coach, Ben Davison, said: “Anthony’s body of work speaks for itself. Dubois is dangerous, but we’re ready.”

The countdown begins now. Promoter Eddie Hearn has promised a “blockbuster” undercard, with Dubois’ promoter Frank Warren teasing a co-feature against a top-10 contender. The O2 Arena is already buzzing, with tickets selling out within hours of the announcement.

Joshua’s camp is tight-lipped about strategy, but insiders hint at a return to his old-school pressure style. Dubois, meanwhile, has mocked Joshua’s recent form, tweeting: “He’s soft now. I’ll break him like the rest.”

For Dubois, a win cements his place as the division’s next big threat. A loss risks derailing his momentum, with potential rivals like Joe Joyce waiting in the wings. For Joshua, the fight is a do-or-die moment. His legacy hinges on whether he can silence the doubters-or if Dubois will deliver the knockout that ends his comeback for good.

The clock is ticking. September can’t come soon enough.
