Tyson Fury could be stripped of his titles after reportedly testing positive for cocaine.
On 23 September, the British boxer pulled out of a fight with rival Wladimir Klitschko which was scheduled for 29 October, according to the Mirror.
He was deemed “medically unfit” for the fight against the Ukrainian.
This was the day after Fury tested positive for cocaine, ESPN reported.
He reportedly underwent a random drugs test in Lancaster on 22 September, which revealed a positive result for benzoylecgonine, the central compound found in cocaine and the marker for a positive test for the banned substance.
Dr Margaret Goodman, president of the Voluntary Anti-Doping Association, said that Fury had the right to appeal request an analysis of a “B sample” at his own expense.
According to the Metro, Fury was already under investigation from the UK Anti-Doping Agency over an alleged use of a banned substance.
Outside the ring, Fury has sparked controversy on a number of occasions.
In May he caused outrage after making homophobic, sexist and anti-Semitic comments in an hour-long video rant.
