WBC heavyweight champion Deontay Wilder (40-0, 39 KOs) is sticking to his guns when it comes to the terms of a potential unification with IBF, IBO, WBA, WBO champion Anthony Joshua (21-0, 20 KOs).
Joshua will return on September 22nd, when he defends his belts against WBA mandatory challenger Alexander Povetkin at Wembley in London.
There is already a date for Joshua's next fight, April 13, also at Wembley.
Wilder's handlers were in talks with Hearn to make a fight for the fall.
The two sides were unable to reach an agreement - and then Joshua decided to go with his mandatory obligation against Povetkin.
Initially, Wilder's team offered Joshua a guarantee of $50 million to do the fight in the United States.
Joshua rejected the terms, and said he was willing to take less in order to stage the fight in the UK.
A counter-offer was sent back, with a guarantee of $15 million to Wilder.
Wilder claims the he accepted the terms and was willing to fight Joshua on UK soil - but he indicates that there were certain details missing from the contract that was issued from Hearn. He says details were missing like like the fight date and venue.
The unbeaten puncher still believes that Hearn and Joshua had no intention of making the fight for the fall.
"We all were going in skeptical about it because you can't trust Eddie Hearn," Wilder told ESPN's "The Boxing Beat."
"Eddie Hearn is not a guy that you can trust, it's just point blank and period about that. Every time we did something, they wanted to come back and serve the ball like we were playing tennis or something. We were trying to get the deal done, as you can see. We did everything, we did everything."
Wilder is going to fight in the coming months, potentially against his current mandatory challenger Dominic Breazeale.
