Eddie Hearn admitted he was taken aback somewhat by recent suggestions, including from Tyson Fury's father John, that the heavyweight unification megafight between Fury and Hearn's fighter Anthony Joshua was nowhere near being finalised.
The elder Fury said over the weekend that he did not think "these cowboys" would get the fight over the line, and that the contract already signed by the fighters means nothing without a venue and a date.
On The Ak & Barak Show (on DAZN and Sirius XM Fight Nation), Hearn responded to the claims.
In response to the claim that nothing has been signed, Hearn said: "What have they signed? A contract!
"Unless they’re trying to talk themselves out of this fight, I’m grafting my nuts off all over the world trying to get this fight done, and all I hear from them is ‘yeah, well, it’s not gonna happen, is it?’
"I said to Arum the other day: 'mate, where’s your mojo?' I’m flying around the world to get this done, and people are saying to me ‘well I heard from this guy that it’s not gonna happen’.
"AJ is in full camp right now. In his mind, Tyson Fury is the only fight that’s happening next. Whoever comes up with the best opportunity, it’s on.
"Hopefully that comes from the other side as well. They signed a deal. Obviously we have to agree on a site offer, but it’s gonna be significant. We’ve already had offers.
"So I don’t like the new noise I’m hearing from that camp. Maybe they’ve been let down before. Maybe they don’t trust people. I don’t know. But for me, I’m not travelling around the world away from my family and going through quarantines and tests (for nothing). It’s a ball-ache.
"So, if you’re with me, as you showed you were by signing the contract, be with us! It’s frustrating, maybe they dont think we’ll come up with the goods, but we will."
Hearn also revealed that not only does he like the idea of the UK staging the first meeting between the two heavyweight champions after all, but that Joshua himself personally prefers Wembley Stadium above all else for the venue, so long as they can fill the stadium up with a capacity crowd by then.
"I want mid-July," said Hearn. "The date depends on many things. For one venue, it’s the back end of July, for one venue it’s the first week of July, for other venues it’s another date, and so on.
"There’s been a bit talk of Wembley which is difficult, but if we got a 100,000 capacity, which the Government are working towards… they’re working on having the European Championships here, which is a huge event, and they want it to be at full capacity. So if we had full capacity in July, Wembley could come back into it.
"It’s not as fruitful as the Middle East, but in AJ’s head this comes back down to the fact that he just wants the fight. I’m not saying he’s not gonna take the best deal, but he wants this fight next more than anything.
"So if it’s 100,000 fans at Wembley, Anthony Joshua is one million per cent signed. But we have to do our job and go around the world and present all the offers to the fighters.
"But Anthony has told me categorically: ‘if it’s Wembley, and it’s full up, I’m in’."
