Tyson Fury has accused Alexander Usic of steroid abuse and Anthony Joshua of being “worthless”.
The 33-year-old WBC heavyweight champion of the world enjoyed training and dining with a sober, nutritionist George Lockhart on Tuesday.
But during his last session of the day, pounding a treadmill, the undefeated Vishal launched a scathing attack on former WBA, IBF and WBO champ Joshua and the brilliant Ukraine southpaw that tore him apart in September.
Fury, who won the same belt from Ukrainian Wladimir Klitschko in 2015, accused Usik of doping up to heavyweight – despite this claim being completely unproven and Fury serving his own doping ban on nandrolone and cocaine use.
Fury erupted on an Instagram Live video: “I can’t believe AJ gave back all heavyweight belts to Ukraine, after all my hard work to get them. You big worthless dodger!
“You let a little steroid guy come up above middleweight and set about yourself and take all your belts.
“A real British Lancaster bomber like me would have to take the useless little steroid head off the belt and get them back to Britain.
“You useless Dodgers! Bring them to me, Gypsy King.
“Bring them to me, and I’ll put them in their place, and take them off the waistband again.”
Usyak, 34, began his career as a middleweight amateur and then went on to become the undisputed cruiserweight king of the pros and then stun AJ.
Unlike Fury, he never imposed a doping ban or suspected illegal activities.
Fury and his team are set to bid the purge with Dillian White on Tuesday as they try to arrange a performance in March.
AJ broke the rematch clause after Usik dominated Tottenham and is planning to run again in April.
SunSport has contacted Team Usyk for comment.
