Eddie Hearn, the promoter for former two-time heavyweight champion Anthony Joshua, has revealed that an offer was received for a long-awaited showdown with Deontay Wilder in Saudi Arabia.

Joshua will first return to the ring on August 12 in a potential rematch with Dillian Whyte.

Saudi Arabia's Skill Challenge Entertainment, who recently signed unified champion Oleksandr Usyk to promotional contract, have sent a formal offer to Hearn for the Joshua-Wilder encounter.

If Skill Challenge have their way, they intend to stage a one-night heavyweight doubleheader, with Joshua facing Wilder and Usyk colliding in an undisputed fight with WBC champion Tyson Fury.

Wilder, a former WBC beltholder, has been inactive since his return last October, when he knocked out Robert Helenius in the first round at the Barclays Center in Brooklyn.

While Hearn has received a formal offer for the Wilder fight, he doesn't have an actual contract.

"We have an offer without a contract. So we need to wait on that contract," Hearn told IFL TV.

Before he can think about Wilder, which is targeted for the month of December, Joshua will gear up for the planned date in August.

Hearn is trying to get a deal done for a rematch with Whyte, who Joshua knocked out in seven rounds in 2015.

"Just discussing it, we had an email conversation today. We've got a call probably later today. Like I said, AJ is fighting on August 12th, we'd like it to be against Dillian Whyte, we'll see if we can make a deal," Hearn said.

Joshua last saw action back in April, with a twelve round decision over Jermaine Franklin. Whyte also had his last fight with Franklin, back in November, as he won a twelve round majority decision.
