Anthony Joshua is set to fight Wladimir Klitschko at Wembley Stadium on April 29.
IBF world heavyweight champion Joshua makes his second title defence against Eric Molina in Manchester next Saturday.
Klitschko, 40, has not boxed since losing the IBF, WBA and WBO belts to Fury by a unanimous decision in Germany in November last year.
The Ukrainian has no plans to fight before facing Joshua, 27, who is unbeaten in 17 pro bouts.
Hearn hopes to confirm the date and venue very soon after Joshua’s bout with Molina, where Klitschko and David Haye will both be at ringside.
Haye, who lost to Klitschko on a unanimous points decision five years ago, said: “It’s always good fun watching a rival in the ring.
“When you are up there close at ringside, you can see every movement, every muscle, you can see the real rhythm, the timing.”
