Hearn stated he would agree to Joshua battling Wilder, potentially in a massive summer unification, provided Whyte is given his opportunity should he defeat Robert Helenius on Saturday night.
Wilder is now fully on board with the idea as he prepares for his own title rematch with Bermane Stiverne on November 4.
“Fighters have obligations to fulfill, they have a job to do, and Dillian Whyte is only doing his job,” Wilder told Sky Sports.
“He is doing what he is supposed to do and, if he is feeling that way, let’s see him.
“Personally, I don’t think he (Whyte) feels that way. He knows he can’t beat me, Eddie Hearn knows he can’t beat me.
“If they want to see that fight, I have no problems fighting that fight, as long as that contract says I have Anthony Joshua next.
“I will go anywhere in the world to show Dillian Whyte who is the best in the world.
“Put Anthony Joshua on that contract and I will come to England.
“Dillian Whyte is an easy fight, I can fight that fight in my sleep, one hand behind my back.
“I am the heavyweight champion of the world, I want to unify the heavyweight division and I won’t stop until I do that.”
Joshua v Wilder provides both fighters with a career-high purse in what would certainly be a sell-out at Wembley Stadium in June or July, whilst Whyte still has to take care of Helenius in order to keep his side of the bargain.
