Fury Sr believes that his boy did enough to triumph in both of his bouts against the Ukrainian last year and implied that boxing chiefs didn't want him to remain as heavyweight world champion for financial reasons.
He told Seconds Out Boxing: "He had them stolen off him, to be honest.
"What can you say? When somebody's paid you a shed load of money they seem to resent letting you stay champion as well…
"They probably didn’t want to pay him the same amount of money again, probably couldn’t afford to pay Tyson that same money again if they let him remain as champion."
Fury Sr suggested that his son is unlikely to reverse his decision to retire because of the injustice he feels and thinks that the heavyweight division will suffer without the appeal of the Gypsy King.
He said: "Listen, for my money, [Tyson] won both fights, they stole his belts off him.
"They’ve taken the biggest seller out of the game, because without Tyson Fury there’s no dance partners.
"This [Usyk vs Daniel Dubois] fight, that’s never going to be a 95,000 crowd, you need a dance partner, and let me tell you, Tyson Fury ‘The Gypsy King’ is the best dance partner anyone can ever have…
"It’s bad business. They think, ‘OK — we’ll rob you today, let the dust settle, offer you a few more quid later on and get you back at it.’
"But guess what? They can’t do that with him now, because he’s had enough. He believes he’s had his belts stolen off him, which he has had. And he thinks, ‘Jog on, there’s no more ‘Gypsy King'."
