Fury's preparations to his third clash against the American were thrown off balance by Covid's and Athena's stay in Liverpool's Alder Hey Hospital's intensive care unit.

Dad John encouraged his son, to keep him busy while he was in the hospital. He went for a run and was stunned when he beat the Gypsy King.
Sky Sports reported that he said: "I went with him to Alder Hey Hospital.
"I told you, 'Look, you have to exercise. Just don't sit here.
"Let's go for some running, you'll feel better afterwards."
"I am 56 years old and 20 stone. I beat him. He was on fire when we went to Liverpool. I thought, "Look at this!"
"My lungs? They were hard to hear. He was unable to complete a three-mile run.

"He said afterward, 'That almost killed me.' That's where he was four weeks before that big night.
Fury never thought of pulling out of the fight, but his old man believes he should have postponed Sin City's showdown.
John said, "He was going do it anyway, so I said, 'OK then. I'll make the best out of a terrible job. I will give him confidence.
"But deep inside, I was concerned because I thought, 'You know what? He shouldn't be doing that'.
Tyson wants to defend his country, knowing that Anthony Joshua lost his belts at home two miles away from his home.
He thought, "You know what? I can't be like that man. I have to do my thing and stand up for my country.
"Win, lose, or draw it's all! "
John was proud of his son's perseverance and said: "I can only recommend my son, there'll nie be another man like Tyson Fury in the sport boxing."
"I told him, 'You're so good, it's frightening!'
"He is the complete package. He has proven everything. There's nothing left for him to prove."
"If he walks away today, he's done with his business, won all the professional titles there are to win.
"He's a remarkable person, so embrace him while you can, because once he's gone it's gone and then you're back at the boring stuff, the losing.
"The belts won't be here because - let's be honest - I don't think they will return to these shores once Tyson's gone.
