Tyson Fury was seen as ‘about 26 Stone’ by Eddie Hearn.
The Gypsy King was in the boxing jungle in 2017, battling with his mental health.
Hearn, 42, had met him in Monaco that year, but did not think he would ever return to title contention.
Lifting the lid on what happened, Anthony Joshua’s promoter told the Boxing Social podcast: “It’s tough because AJ is a close friend of mine.
“I always wanted those two to fight, AJ being our guy and I could just imagine killing him.
“With Tyson, I flew him to Monaco and he was about 26-stone.
“He was sweating, and I just thought to myself ‘You’re never fighting again’.
“So the plan was to have two easy fights, by that we mean the likes of Sefer Seferi which he did, but then do a move and fight like Manuel Charr.

“I was just thinking… if I knew he was going to fight Sefer Seferi, someone else and then Deontay Wilder, I would have ended it all.”
Fury, 33, took care of Ceferi and Francesco Pianetta before taking on Wilder in 2018.
After an explosive draw with the Bronze Bomber, Fury defeated Otto Wallin in a bloody fight – before beating Wilder twice and claiming the WBC belt for good.
Despite Fury’s incredible success, Hearn insists he has no regrets about his decision.
He continued: “I’m not sorry.
“But would I love to join Fury-Wilder? Of course, this is my bread and butter!
“That’s what I live for, but at the same time I know we had Dillian White and Derek Chisora and people like that, but trying to have both Fury and AJ would have been a really weird situation.
“You can’t say you don’t respect a fighter and a character like Tyson Fury because he’s become a big star.”
Joshua’s chances of finally facing Fury will depend on his rematch with Oleksandr Usyak in the spring.
Gypsy King, meanwhile, we’ll take on another matchroom fighter in Dillian White.
