Any prospective fight between Anthony Joshua and Tyson Fury is "miles away", according to promoter Eddie Hearn.
IBF, WBA and IBO heavyweight champion Joshua picked himself up off the canvas to knock out Wladimir Klitschko in the 11th round of Saturday's epic bout at Wembley.
Joshua's fellow Brit Fury stunned Klitschko in Germany with a points victory back in November 2015, but has not fought since amid reported mental health problems and is currently without a boxing licence.
Saturday's dramatic win over Klitschko took Joshua to 19-0, all by knockout, and afterwards he called out Fury (25-0).
Fury responded with "let's dance" on Twitter, before claiming he could beat Joshua with one arm behind his back, but Hearn says any realistic possibility of the two doing battle remains a long way off.
"We are desperate for that fight because AJ thinks he wins comfortably, it is a great fight and it is the biggest fight out there," Hearn told talkSPORT.
"But we can only concentrate on AJ's career and guiding him.
"He [Fury] is miles away from fighting. He is in a terrible physical way at the moment. He doesn't have a licence, he needs to go back to the [British Boxing] board, and he is under investigation for [an alleged] failed [doping] test.
"There is no one that wants to see him back more than me, but it is miles away. He is not the next fight because he won't be ready in time."
