Eddie Hearn has told ESPN that Tyson Fury needs to find "reality" if the former heavyweight world champion is genuine about fighting Anthony Joshua.
Fury stated on Twitter that Joshua would accept a 40 percent share of any potential fight and the undefeated IBF WBA champion would need to be announced first and be first in the ring.
However, Hearn dismissed Fury's proposal as "a very funny joke" and told the lineal heavyweight champion to show that he is serious about returning to the ring.
"We have to deal in reality right now," Hearn told ESPN. "We would love to box Tyson Fury. Nowhere near those offers [of 40 percent] of course, but we have to deal with the reality that he is available and he's in front of us.
"We are very consistent. We are not going anywhere. We want to go through everybody and we are going nowhere. He's got to get himself in shape and get himself into the position to fight. He talks the talk, let's see the reality."
Meanwhile, Hearn confirmed a deal for Joshua (20-0, 20 KOs) to fight WBO champion Joseph Parker is close to completion and a fight could be announced in early 2018.
"We're in good shape [with securing a fight with Parker], but it's not done yet," Hearn added.
"Over the Christmas period, the turkey will be put aside and hopefully early January we will have a positive announcement for AJ's next fight. March 24, March 31, April 7. Those dates are all in play."
