Joseph Parker, former heavyweight champion, stated that traces of cocaine found in his UK Anti-Doping (Ukad) test were due to exposure from his nutritionist.

The nutritionist, a regular cocaine user, confirmed to investigators that he had used the substance daily prior to Parker's fight against Fabio Wardley on October 25, 2025. Parker expressed his relief at being cleared to return to the ring and thanked his supporters.

"Former world heavyweight champion Joseph Parker argued to British anti-doping authorities that his nutritionist's cocaine use caused a positive drug test after his bout with Fabio Wardley last October. UKAD said Thursday it imposed a three-month ban which was deemed served because the 34-year-old New Zealander had been suspended since late November. Parker is free to fight again after the anti-doping organization accepted that “any ingestion of cocaine by Mr. Parker occurred out-of-competition only and in a context unrelated to sport performance.”
