World heavyweight champion Deontay Wilder claims he has agreed to fight Britain’s Anthony Joshua in the UK.
The American, 32, holds the WBC title and wants a unification bout with Joshua, the WBA, IBF and WBO champion.
He tweeted: “The $50m offer for him to fight me next in the US is still available. Today I even agreed to their offer to fight Joshua next in the UK.”
Joshua’s promoter Eddie Hearn told Sky Sports he will send the contracts but wonders if Wilder’s claim is “bluster”.
He added: “It’s all come as a bit of a shock that Deontay’s finally come back to us on the offer and seems to accept the terms.
“One thing I can tell you is that by the end of this week Deontay Wilder will have a contract in front of him and we’ll see if he’s real.”
Hearn has previously criticised the Wilder team for appearing to do their business via social media, insisting “deals are made in the boardroom, not on Instagram”.
“If he prefers the fight in the UK, the ball is in their court. It’s up to them to choose,” Wilder added.
