TYSON FURY accused Oleksandr Usyk and Anthony Joshua, respectively, of steroid abuse.
The WBC heavyweight champion, aged 33, enjoyed quiet Tuesday training and eating with George Lockhart.
Fury also attacked Anthony Joshua, who lost his belts to Usyk last September
The undefeated giant took to the treadmill for his final session and launched a tirade against Joshua, an ex-WBA, IBF, and WBO champ, and the brilliant Ukraine southpaw, who defeated him in September.
Fury, who in 2015 won the same belts from Ukrainian Wladimirklitschko, accused Usyk, despite this claim being completely unproven and Fury having already served his doping ban for nandrolone use and cocaine use.
Fury screamed in an Instagram Live video, "I can't believe that AJ has given Ukraine all the heavyweight belts back after all my hard work to get them. You big useless dosser!
"You've allowed a little steroid guy to come up from middleweight, set about you, and take all of your belts.
"It will take a real British Lancaster Bomber like me to relieve the useless little Steroid Head of the Belts and bring them back to Britain.
"You useless dossers! They are yours, Gypsy King.
"Bring them to my place, and I'll put them in their places and take them off the belts."
The 34-year-old Usyk started his career as a middleweight fighter. He then went on to be the undisputed champion in cruiserweight and was then able to shock AJ.
He has not been subject to a doping ban or been suspected of illegal activities, unlike Fury.
Fury and his team will be bidding on Tuesday with Dillian Whyte for purse bids as they attempt to organize a March showdown.
After Usyk's defeat at Tottenham, AJ took the rematch clause and is now planning an April rematch.
SunSport reached out to Team Usyk in order for comments.
