According to Eddie Hearn, promoter for WBO, IBO, WBA, IBF heavyweight champion Anthony Joshua, there is no communication from the handlers for WBC champion Deontay Wilder.

This coming Saturday night at Wembley in London, Joshua will defend his titles against mandatory challenger Alexander Povetkin.

Wilder (40-0, 39 KOs) is slated to fight again in the coming months, against undefeated lineal champion Tyson Fury.

Joshua (21-0, 20 KOs) is already scheduled to defend his titles on April 13, also at Wembley.

More than anything, Hearn would like for Joshua to face Wilder on that date.

The two sides were in talks for this coming Saturday for several weeks, but they were unable to agree on the financial terms - and then the WBA ordered Joshua to face Povetkin.

Hearn claims that he's trying to make the fight - with no response coming in from the other side, including no traction from Wilder co-manager Shelly Finkel.

"If there's even a chance that an undisputed title fight could happen in April, you've got to at least talk about it. Maybe they don't use emails - maybe Shelly uses carrier pigeons or smoke signals. I'm going to strap a note to a pigeon's leg and send it to New York," Hearn said to Sky Sports.

"It's not a case of saying they're concentrating on Fury. It's the promoters' job to plan ahead. It's frustrating because there's limited time to make the fight. People must be realising that they don't want the fight because, if they did, why haven't they replied?

If Hearn is unable to secure Wilder - then the focus will fall on a rematch between Joshua and Dillian Whyte.

Back in December 2015, Joshua stopped Whyte in the seventh round. Whyte was able to hurt Joshua in the early going and then faded in the later rounds.

"At the moment [Whyte is the frontrunner], yes," explained Hearn. "[Whyte] is first going to fight in December. We are negotiating, talking for December 22 at The O2.

"Making a fight when the fighters don't particularly like each other is very difficult. But generally people are bright enough to swallow their pride, and get it done. There's a good chance."
