Peter Fury has confirmed that Tyson Fury has failed a drugs test after testing positive for cocaine, but his family still believe he can have a career in boxing.
Peter Fury, Tyson's uncle and trainer, insists the WBA and WBO world heavyweight champion can still have a career in boxing, even though he could now face a ban and be stripped of his belts.
Fury has revealed he is suffering from depression and Peter Fury, as well as the 28-year-old's father John, does not think he has been given the support or respect he deserves.
Peter Fury told Sky Sports News HQ: "VADA has given official confirmation that he has failed the drugs test on traces of cocaine in his system.
"It just highlights for me the despair and the depths that he has gone to, to even contemplate such a low-life result as turning to that, because we all know what that does. It doesn't help any human being at all, it puts you in a worse state.
"So basically to have nobody to turn to, nobody to discuss his feelings with, obviously it looks like he has turned to that. So again this is a sad, sad situation and I can only put it down to that.
"If Tyson was in his sound state of mind and he was doing that, our relationship would be terminated because I can't stand that behaviour. But I know where he is at."
Peter also revealed his nephew had been battling against depression for some time despite it only recently being made public.
He added: "This has been going on for quite a few years - he's been coping with it up and down, up and down - and I think recently since winning the world title that added pressure. I think with the allegations as well that completely tipped him over the edge.
"And according to his psychological reports he needs treatment as well to build his reserves up, whatever that means."
John Fury, meanwhile, has issued a rallying call to boxing fans and the authorities to get behind his son as he embarks on his recovery.
"It's early days yet. He starts his treatment very, very soon," he said.
"With what's happening at the minute, and what he's doing at the minute, what he says and does cannot be taken any notice of because he is not in control of his own actions. It's not me saying that, that's a professional doctor.
"Most definitely [he can recover] with a bit of help and the right kind of respect and help from Joe Public and the powers-that-be in boxing.
"He loves boxing, it's his life and I don't see why there can't be a recovery. But I don't see a recovery if nobody can help, it's not just a doctors' thing or a family thing. He needs boxing and the people around him to respect him."
