Former world heavyweight champion Joseph Parker denies taking any prohibited substances after testing positive for cocaine following a Voluntary Anti-Doping Association (Vada) test in October. Parker, who was beaten by Fabio Wardley on the same day, acknowledged the "adverse finding" and emphasized his surprise at the results. The New Zealander has stated his cooperation with the investigation and expressed confidence in clearing his name of any wrongdoing related to performance-enhancing drugs.
