Eddie Hearn, promoter for IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua, does not want to wait until December 1 to begin negotiations for a potential unification with WBC champion Deontay Wilder.
Wilder (40-0, 39KOs) will make a defense of his title in a high profile fight against Tyson Fury on December 1 at Staples Center in Los Angeles, California.
Joshua (22-0, 21 KOs), last month, knocked out Alexander Povetkin in the seventh round in a WBA mandatory defense at Wembley in London.
Joshua is scheduled to fight again on April 13, back at Wembley.
The focus right now, is to start negotiations for a unification with Wilder.
Wilder's team would rather begun the talks in the aftermath of the Fury fight.
Because the negotiations will be long and complicated, Hearn wants to at least set down a tentative set of terms for the fight, in order to understand where both sides stand on the matter.
"What I want his legacy to be, which is something he shares, is to be one of the greatest heavyweights of all time, to be the undisputed champion is the ultimate goal, it might happen as soon as April 13," Hearn told Sky Sports.
"We are starting the conversations now, I don't want to wait and start from scratch on December 1 as then we'd be under pressure, I want to get a feel now and see what deal Wilder's team may accept and then we can get somewhere close.
"It's amazing to see this young man [Joshua] go from his O2 debut as a young kid out of the Olympics, to where he is now, the biggest figurehead in the sport of boxing, a trailblazer and the biggest idol, icon and ambassador in the sport. I'm very proud of him."
If the Wilder fight is not done, then Dillian Whyte is the frontrunner to face Joshua on the date. Joshua stopped Whyte in the seventh round back in December of 2015.
