Joshua, 26, defeated Charles Martin on April 2 to capture his first world title and Hearn wasted no time setting up another clash at the same O2 Arena venue.
Hearn is currently scouring the new IBF rankings for an opponent for Joshua in two months’ time, after which a four-belt unification with UK rival and current WBA/WBO/IBO title holder Fury could follow despite interest from former WBA king David Haye.
“I think the next fight after June 25 could be Tyson Fury,” Hearn told Sky Sports.
“David Haye is a big fight. There is no real carrot with a David Haye fight, other than it’s a huge fight with a load of money to be made.
“I think AJ wants the belts, he wants to unify the division. To do that, you have to beat Tyson Fury. We feel like Tyson Fury is a much easier fight than David Haye.”
Joshua favouring Fury means the winner of the mandatory clash between Joseph Parker and Carlos Takam faces a wait to land a stipulated challenge.
Unifications are above any mandatory scenario for Joshua and would see Parker or Takam, who fight on May 21, put on the backburner until 2017 at the earliest.
