Tyson Fury has now tested positive for cocaine for the second time, having undergone two drug tests on September 21 and 22 respectively.
The first set of results appeared last month, days after the British boxer withdrew from a championship rematch against Wladamir Klitschko for the second consecutive time after defeating the Ukranian last year for the WBO and WBA titles.
Fury's trainer and uncle Peter Fury has come to the defence of his nephew, stating that his use of cocaine was primarily to battle depression, something the 28-year-old has been struggling with for a few months now.

Previous reports claimed that Fury had been suffering from mental illnesses, depression being one of them, forcing him out of his scheduled matches against Klitschko.
The current champion is reportedly undergoing treatment and rehabilitation in a bid to get back to regular boxing, but is also the subject of a hearing from the British Boxing Board of Control (BBBofC), where the possibility of stripping the boxer's license, and titles as a result, will be discussed.

In the wake of these controversies, Peter Fury has provided support for Tyson, saying: "Personally I don't believe he's had drug issues going back over six months.
"If he's done something it's been recent. I don't think he's got a drug problem at all."
The trainer adds: "Whatever he's taken will be a result of the depression.
"The way he's been received since he won the world title, to him, in his mind, he wasn't recognised in anywhere near the way he should have been. It's a combination of all of this that put him into depression.
"He just wants some space totally away from boxing, which is understandable."
Therefore, Peter does acknowledge his nephew's need for some time off to recover from his depression, which could justify the BBBofC's efforts to withdraw his license.
In a recent interview with Rolling Stone, Fury spoke about his drug use as well as his desire to commit suicide, some of which have been claimed by his uncle to be "untrue".
Peter Fury is unsure what to believe from the interview given the fragile mental state of the boxer.
The trainer said: "There were things in the interview which were not correct. He said in his interview that he hadn't been training at all, he hadn't done any training for five months, well that's totally untrue."
Peter added: "Just how much is the truth? Your guess is as good as mine."
According to his uncle, Tyson has been training at his boxing facilities in Bolton, Lancashire and at a local sports club, as well as with a strength and conditioning trainer.
However, the boxer has seemed far from enthusiastic or motivated during these sessions, as claimed by Peter.
Amidst the impending decision from the BBBofC, Peter believes that Tyson could return to competitive boxing in 2017, once he completely recovers from his illnesses.
