1:45 Eddie Hearn hopes the Anthony Joshua-Deontay Wilder fight will be agreed Eddie Hearn hopes the Anthony Joshua-Deontay Wilder fight will be agreed

Anthony Joshua will sign a contract for a potential fight with Deontay Wilder at Wembley on April 13, says his promoter Eddie Hearn.

The unified world heavyweight revealed last week that his next two fights will be at the national stadium, with a WBA mandatory title defence against Alexander Povetkin expected to be staged on September 22, and Joshua is due to return on April 13 in front of a bumper 100,000 attendance.

Hearn remains hopeful that Wilder will be in the opposite corner on that date and revealed that Joshua will actually sign the contract now in a bid to kick-start negotiations again with the WBC champion's team.

"I'm pretty confident," Hearn told Sky Sports News. "I think at the moment he's [Wilder] throwing his toys out of the pram, and eventually we hope he'll come to his senses.

Anthony Joshua says let's sign the contract and put it in front of them, rather than them thinking that we're bluffing for some bizarre reason, or we don't want the fight. Eddie Hearn

"I spoke to Anthony yesterday and I think what we're going to do is all the terms that were agreed by Deontay Wilder have now been put into the contract. They've had them now for over a month, and they haven't done anything, so I think what we're going to do, we're going to sign the contract.

"Anthony's going to have a press conference for his next fight next week and he'll be in America as well, and it will be good to go out there and say we've done all we can.

"You've agreed these terms, we've now even signed the contract, so fingers crossed, April 13 at Wembley will be Joshua against Wilder."
