Former world heavyweight champion Joseph Parker is cleared of breaking anti-doping rules after a UK Anti-Doping (UKAD) investigation concluded that traces of cocaine found in a test were caused by exposure to his nutritionist. Parker, a 34-year-old New Zealander, received a provisional suspension after urine tests following his bout against Fabio Wardley in London in October showed cocaine in his system. UKAD later imposed a three-month ban, which was considered served because Parker had already been suspended since late November. Multiple outlets report that Parker argued during the anti-doping process that his nutritionist had used cocaine and that Parker’s positive result resulted from out-of-competition, non-performance-related exposure. UKAD accepted that explanation, citing that any ingestion occurred out of competition and in a context unrelated to sport performance. As a result, Parker is free to fight again. The case centres on UKAD’s findings regarding the likely source of the positive test rather than evidence of deliberate use by Parker.
