Anthony Joshua was contractually bound to drug testing from the moment he signed for his fight with Tyson Fury, but Fury faced no matching obligation, promoter Eddie Hearn has confirmed.

Hearn said the testing protocol built into the fight fell apart because the language in Joshua's contract was never mirrored in Fury's. "It wasn't adhered to in its form. I don't actually necessarily blame Tyson Fury for that. As we've found out on many occasions, what's in AJ's contract is not necessarily in Tyson Fury's contract," Hearn said. He added that testing was supposed to begin when the original contracts were signed, but that never happened for Fury's side, and that he does not believe Fury was ever obligated to enroll early. "This is not me saying, 'He didn't enroll.' I don't think he was obligated to enroll [in his contract], but in our contract, he was," Hearn said.

Why the testing gap happened

Big heavyweight fights like this one get built on separate promotional deals rather than one shared master contract. Matchroom negotiates for Joshua, Fury's team negotiates for Fury, and that split structure is exactly where a provision as important as drug testing can slip out of alignment. Joshua's side put him into a testing pool tied to the signing date, committing him to scrutiny through the entire training camp and beyond. Fury's side never wrote in that same early start, which meant one fighter could be tested year round while the other was not held to the same clock.

What it means for the fight

Hearn was careful to frame this as a paperwork failure rather than an accusation, making clear he does not blame Fury personally and that Fury broke no agreement of his own. The issue is that Matchroom let its own fighter sign into a stricter standard than the one governing his opponent, and that mismatch undercuts the deterrent value testing is supposed to provide in a fight built on heavyweight power. By putting the discrepancy on the record, Hearn also puts pressure on Fury's camp to close the gap and match Joshua's terms before the two heavyweights get much closer to fight week.
