The Manchester heavyweight produced a dominant performance against Chisora, who was rescued by his corner after taking sustained punishment at London’s ExCeL Arena.
The victory could have earned Fury a crack at Wladimir Klitschko???s WBO belt, but his preparations for the crucial clash were severely disrupted when he suffered a chest infection.
A summer fight had already been shelved after Chisora hurt his hand and Fury was determined to press ahead with the rescheduled bout.
“Nobody knows Tyson hadn’t trained for the past three and a half weeks coming into this fight,” said his trainer Peter Fury.
“Tyson had a virus that put him bed-ridden. He’s had flu injections, been up and down to the doctors, I took him to my place and put him in bed for three or four days.
“Last week he started to feel better and two days before this fight he said, ‘listen I feel absolutely okay’.
“There was talk at one time of pulling this fight but we have to be on death’s door to pull a fight.”
The 38-year-old Klitschko holds three of the world titles and has not been beaten for over 10 years, but the Fury camp are confident that he can compete with the division???s best.
“Tyson will bring back a world title for Britain,” said his uncle Peter. “The thing with Tyson Fury is you don’t know who is turning up.
“That’s why he has a big advantage – how can you prepare for someone like him? He’s able to switch his tactics up, he’s got that much potential.”
“I don’t think anyone thought Tyson Fury could do what he’s done to a fighter like Chisora.
“Tyson is majorly talented and people need to wake up. Just because he’s 6ft 9, looks a bit clumsy now and then, goes in swinging when he hasn’t got his trainer in the corner – Tyson is a serious threat on a world level.”
Promoter Frank Warren revealed how he urged Chisora???s corner to act after Fury piled on more punches in the 10th round.
“I told (Chisora’s trainer) Don Charles to stop the fight,” Warren said.
“He was nine rounds behind at that stage and it didn’t look like he was going to knock him out. What was the point? The punishment he was taking to try get his shots off was not somewhere I wanted him to be.???
