Self-proclaimed Gypsy King Fury is now still suspended after failing two drug tests since he shocked the world by beating Wladimir Klitschko almost two years ago.
After a rematch with Klitschko twice fell through in early 2016, Fury admitted to substance abuse and has licence rescinded by the British Boxing Board of Control.
With Fury reportedly eyeing a return to boxing in 2018, Joshua - not known for badmouthing other fighter - claimed that there would not be a repeat of the uncharacteristic outburst until the pair meet in the ring.
Fury is now awaiting a UK Anti-Doping hearing so that his suspension can be lifted and his boxing licence returned.
But the 29-year-old looked a long way from his best as he got back to the gym on Monday, as he fooled around with his trainer, showboating for the camera in a light training session on Monday afternoon.
"The only fear is that Joshua doesn't get beat beforehand", Fury added.
Hearn stated he potentially wants Wilder and Joshua to share a bill and may even be prepared to allow Wilder to fight Parker on the same card in order to put all the belts in one place. And he really thinks that's the fight that should be made. I'd die first! Punk'.
Fury vowed to return to the top of the pile in a recent "open letter" he penned to the now-retired Wladimir Klitschko, in which he sounded a warning to Klitschko's last conqueror Anthony Joshua. "You just fought a midget the other day in a hard fight. You want to practise on a bit more speed, a bit less power".
"I try to be professional but remember this is a fighting sport and you have to meet fire with fire now and again".
Fury saw the video and responded to the remark, tweeting: '10 men like you AJ couldn't make me put my tail between my legs.
I wouldn't expect anything more from you guys, but deep down you know what happened in there and by the way I'm going to deal with your little brother AJ in the same fashion as I dealt with you, play with the bitch.
