That’s according to Eddie Hearn, who also admits Adam Kownacki has “pretty much” ruled himself out.
Joshua was set to go exchange blows with Jarrell Miller in New York but ‘Big Baby’ failed a Voluntary Anti-Doping Association drugs test on March 20 and has since had his licence revoked.
Miller’s team have spoken to the New York State Athletic Commission and want them to test sample B, with sample A having been the one showing ‘an adverse finding’.
The undefeated American was set to pose a real test for Joshua as he looks to defend his WBA, IBF and WBO heavyweight belts and continue his quest to become the first undisputed champion of the division since Lennox Lewis in 2000.
Joshua’s promoters, Hearn’s Matchroom, now have six weeks to source an alternative opponent with Tyson Fury and Deontay Wilder already off the table.
Luis Ortiz has also ruled himself out, declaring a lack of preparation time, while Hearn says Kownacki has joined him and that Whyte will not get his rematch with his compatriot.
Speaking to iFLTV about the situation, Hearn explained: “If it was two weeks, we’d be f***ed. There’s a lot of heavyweights that are training, they don’t have to make weight.
“We started reaching out to heavyweights Tuesday, it’s a lot of time. Some people use the time as an excuse for not taking the fight.”
Asked if Kownacki has withdrawn from contention, he said: “Publicly yeah, pretty much.”
Hearn then added: “Kubrat Pulev’s guys I’m speaking to. One of the first calls I had was with Jay Jimenez, who is Luis Ortiz’s guy. He said, ‘We’re not going to be ready.’ I said, ‘You’ve got time mate.’
“Why can’t he be ready in six weeks? That’s what I said. He was one of the first people I spoke to. I said, ‘Look, it’s seven weeks.’ It will do, that’s what happens.
“There’s been a couple more that have come on. There will be as well because people will sit at home and go, ‘Do you know what? I’ve seen this lovely car.’ Do you know what I mean? ‘Seen this lovely house.’
“Dillian’s boxing in July, there’ll be an announcement very soon on that. He ain’t fighting June 1st at Madison Square Garden. I spoke to him yesterday, he told me a number he wanted. It wasn’t tongue-in-cheek.
“I’d like an American, we’d all like an American. Or someone that has boxed in America, has profile in America, etcetera. Michael Hunter is on the list.
“Trevor Bryan, not really. The first call I had was Don King, when Dan Rafael broke the news, a minute later I had a voice mail off Don King. It said, ‘I heard your news, you need some help, I’m here for you my man.’
“What a hustler. Trevor Bryan, No 1 WBA but hasn’t got the profile for that fight.”
