Parker claimed failed drug test was caused by cocaine use of nutritionist

Former heavyweight world champion Joseph Parker claimed a failed drugs test that resulted in him being suspended from boxing was caused by exposure to cocaine being used by his nutritionist, according to UK Anti-Doping (UKAD).

Parker returned an adverse analytical finding (AAF) for benzoylecgonine, a metabolite of cocaine, during a routine UKAD test shortly after his surprise defeat to Fabio Wardley in London on October 25 last year.
