A unification between Joshua and Deontay Wilder appears to be a million miles away. Team Wilder aren't even returning Hearn's emails.
"Well, to say Deontay Wilder's camp has gone quiet, that's saying it lightly," the Matchroom boss said to Sky Sports.
"Probably up to six unanswered emails now. In fact, I sent one a couple of days ago, saying I just want to check these haven't gone into your Spam items.
"It is frustrating because you walk out there on the street 'When's he going to fight Deontay Wilder?' It's like, whenever they want it, but sometimes the public want to believe a fighter on Instagram all day.
"If they wanted the fight, they would talk to me.
"They're not even talking to us. We've made offers, we've made percentage splits. Everything we can do, to try and make that fight."
Hearn reveals Fury is a more likely opponent than the undefeated-American WBC world champion.
"I think right now, there's more chance of fighting Tyson Fury. There's a man that knows he can have this fight, if he wants it. I've spoken to him. He knows if he wants to fight Joshua, it can happen April 13," he added.
"All those guys that I've mentioned, particularly Wilder, Fury and Whyte - that fight is there for them."
Dear God wilder.
Guess it's down to fury. Does he take on the champ or go for a rematch no one wants ?
