Eddie Hearn claims a contractual flaw has resulted in Tyson Fury 'not adhering' to the drug testing protocol for his mega fight with Anthony Joshua.
Joshua and Fury have already signed individual agreements with Saudi powerbroker Turki Alalshikh to meet at the back end of this year.
However, discrepancies in their respective deals have delayed an official announcement.
While Alalshikh and streaming service Netflix had pushed for the fight to be staged in the United States, Joshua has it written into his contract that the Battle of Britain must take place in the UK.
Joshua and Hearn have stood firm on their stance, with the bout now looking set to be announced for Cardiff's Principality Stadium on December 11.
Fury had no such clause in his deal, causing a great deal of confusion on 'The Gypsy King's' side.
And according to Hearn, the location isn't the only difference in both men's contracts.
The Matchroom Boxing mogul also declares that Joshua has been legally bound to enrol in drug testing ever since putting pen to paper, while Fury has not.
Hearn reveals contractual flaw in drug testing
âÂÂThe drug testing protocol was the same as what has always been in there," Hearn told assembled media at the Pat Brown vs John Hedges post-fight press conference on Saturday night.
"It wasnâÂÂt adhered to in its form. I donâÂÂt actually necessarily blame Tyson Fury for that.
"As weâÂÂve found out on many occasions, whatâÂÂs in AJâÂÂs contract is not necessarily in Tyson FuryâÂÂs contract.
"Testing was supposed to start when the original contracts were signed, and it didnâÂÂt for them.
"And I donâÂÂt think [Fury] had in his contract that it had to start then.
"So this is not me saying, âÂÂHe didnâÂÂt enrol.â I donâÂÂt think he was obligated to enrol [in his contract].
"But in our contract, he was obligated to enrol.
"There have been many issues along the way with the contract that we have let slip and ride because we want to stay in the fight and make sure it happens."
As Hearn lays out, this is not evidence that Fury broke an agreement, nor does it make him complicit in any wrongdoing.
But it does shine a light on the failures of whoever drafted the contracts.
