Tyson Fury’s trainer has confirmed the WBA and WBO heavyweight champion is “seeking help” for issues arising over what he believes to be a “witch-hunt” against the boxer.

Fury was due to defend his belts against Wladimir Klitschko next month but has been declared medically unfit, postponing the rematch for a second time.

Peter Fury, Tyson’s uncle and also his trainer, claims his nephew is “at an all-time low” following a wave of negativity and allegations of doping against the 28-year-old.

“I think it’s a culmination of things,” Peter Fury told iFL TV.

“When he won the world title the way he was treated, he said to me: ‘I came back off the boat, I picked up the paper, I expected to be celebrated.’ Straight away, he said, the hate campaign started.

“He was complaining about it a lot but said: ‘Okay, we’ve got to accept it. I’ve won the world title and this is how I’m treated. There’s almost been a vendetta against me since I’ve won it.’

“On many occasions he’s asked: ‘What’s it for? Because if I’m not being credited for the work I’ve done and what I’ve achieved, why am I bothering?’

“So I think it’s created a lot of negativity in him as a person and it’s just the lack of respect he’s received on a global scale, it’s obviously had an effect.

“I think that, because of the witch-hunt against him and recent allegations, it’s put him over the edge. He said: ‘If this is what boxing’s doing, I don’t want it.’”

A statement is expected to be released today clarifying the situation, and Peter Fury added: “There’s a lot to be answered for. It’s very disappointing for me because we’ve got a super talent here and he’s been driven underground with it, almost so he’s at breaking point.

“He is seeking help... Basically nothing means anything. He’s at an all-time low. I think he’s always been a little up and down in the past, a bit volatile, always has been, but never like this.”
