Fury, 27, was due to appear alongside rival Klitschko in London last week but used several excuses for a no-show that left a packed room full of media and members of both teams in the lurch.
A UK Anti-Doping hearing set for after the fight still hangs over the bout with Fury v Klitschko just a month away, whilst the champion’s cancellation of their original meeting in July doesn’t fill Hearn with confidence the encounter will be done and dusted in time for Joshua to face the winner in the summer of 2017.
“The Tyson Fury circus continues, the latest being his no-show at the press conference to promote his rematch with Wladimir Klitschko,” said Hearn in his Daily Mail column.
“I’m not sure about the legitimacy of his excuse that he was stuck in traffic and it does not fill anyone with confidence this fight will happen.
“Personally, I hope it does because we want the winner for Anthony Joshua next summer and those belts need to get moving,” he added.
Undefeated ruler Joshua is set to return to the ring in Manchester on November 26 before a scheduled first bout of the New Year in March.
Hearn is then eyeing Wembley Stadium for a massive unification with Fury, Klitschko or WBC ruler Deontay Wilder outdoors but could turn to ex-title holder David Haye should all belt options fail to materialize.
Haye, 35, had promised he would be battling Shannon Briggs in September until the American eventually gave up his pursuit when the Brit went quiet on the deal and is still yet to announce the continuation of his comeback.
A fight opposite Joshua still holds massive appeal in the UK, although Haye would need to step up his opposition in order to prove to the public he’s worth another Box Office punt.
The last time Haye appeared on British pay-per-view against Audley Harrison in 2010 put an end to the format on his home soil for years and Hearn is aware it would be a big risk to put the ‘Hayemaker’ back in that kind of spotlight.
