In the past, ‘Dynamite’ has been accused of quitting fights including in his 2020 defeat to Joe Joyce, and his original loss to Usyk three years later.
Having failed to beat the count this time around after Usyk floored him with a left hook, the questions once again arose.
The likes of Tony Bellew and Joseph Parker have suggested to talkSPORT that he opted to quit, particularly given the towel was thrown in from his corner.
But Fury has hit back at those claims in a fiery video on his social media, where he even offered to work alongside his fellow Queensberry Promotions star.
He said: “Hi guys, quick one I keep getting asked about this Dubois stuff and quitting etc.
“The facts are young Daniel did his best against one of the greatest champions that’s ever been and it wasn’t good enough.
“He got put down twice? What do you want him to do, die in the ring?
“There’s no first place for betting battered to f**k and still losing. The lad did his best, he wasn’t going to win, he was better of getting out of there.
“There is a lot of jealousy in boxing. Especially when individuals making a lot of money. A lot of jealous fighters.
“There are now cowards in boxing. So all the credit goes to Daniel. He worked his b****ks off since the age of 8.
“Now he’s sitting at home as a multi-millionaire. Daniel if you ever get to see this, chin up son. Everybody is proud of you.
“You’ve gone from a kid to a man to being the world heavyweight champion and boxing in front of 100,000 at Wembley.
“If you ever want to do any training, come to Morecambe any time you want kid. There is no jealousy here.
“There’s no putting people down here, they are dirty jealous w****rs. I call them dream crushers.”
Fury himself lost to Usyk twice and knows exactly what it is like to be written off by the boxing world.
Dubois now faces a challenging rebuild, with several question marks over his overall display against Usyk.
Much goes down to the brilliance of the Ukrainian, who was sensational and is now ranked by most as an all-time great alongside the likes of Lennox Lewis.
But it has emerged that Dubois’ preparations also played a part, with a party thrown by his father on the day of the clash.
He was also late to the arena, and former world champion Bellew believes he simply didn’t want to continue.
He added to talkSPORT: “When he gets into these really hard moments in a fight, that’s when the real Daniel comes out. The real Daniel doesn’t want to fight.
“I’m sorry to say that. It sounds bad and really harsh, but that’s just the truth.
