TYSON FURY has accused Oleksandr Usyk of steroid abuse and Anthony Joshua of being ‘useless’.
The 33-year-old WBC heavyweight champion of the world enjoyed a quiet Tuesday, training and eating with nutritionist George Lockhart.
But during his last session of the day, while pounding a treadmill, the undefeated giant launched a tirade at former WBA, IBF and WBO champ Joshua and the brilliant Ukraine southpaw who dethroned him in September.
Fury, who won those same belts from Ukrainian Wladimir Klitschko in 2015, accused Usyk of doping his way up to heavyweight - despite that claim being utterly unproven and Fury having served his own doping ban over nandrolone and cocaine use.
Fury barked on an Instagram Live video: “I cannot believe that AJ has gone and given Ukraine all the heavyweight belts back, after all my hard work of getting them. You big useless dosser!
“You’ve let a little steroid man come up from middleweight and set about you and take all your belts.
“It is going to have to take a real British Lancaster Bomber, like me, to go and relieve the useless little steroid head of the belts and get them back to Britain.
“You useless dossers! Bring them to me, the Gypsy King.

“Bring them to me and I will put them in their place and relieve them of the belts again.”
Usyk, 34, did start his decorated career as a middleweight amateur before going on to become undisputed cruiserweight king in the pros and then stepping up to stun AJ.
Unlike Fury he has never served a doping ban nor been under suspicion of any illegal activities.
Fury and his team are set for purse bids with Dillian Whyte on Tuesday as they try to arrange a March showdown.
AJ snapped up the rematch clause after Usyk dominated him at Tottenham and is planning an April rerun.
SunSport spoke to a member of the Usyk's team who found Fury's baseless comments utterly laughable.
