Former boxing champion Joseph Parker says failed drug test a result of nutritionist’s cocaine use

Former world heavyweight champion Joseph Parker has attributed a failed drug test to the cocaine use of his nutritionist, according to arguments presented to British anti-doping authorities. The positive test followed Parker's bout against Fabio Wardley, which took place last October.

Parker, who lost the October 25 fight, offered the explanation regarding the presence of the substance to regulatory officials. The incident places the boxer's recent athletic performance and testing results under scrutiny by anti-doping organizations in the United Kingdom.
