Joseph Parker cleared after nutritionist-linked cocaine test
8/7/2026, 9:26:59 PM
Core Event: Positive test and suspension lifted
Former WBO heavyweight champion Joseph Parker tested positive for benzoylecgonine, a cocaine metabolite, in a UK Anti-Doping (UKAD) urine sample taken on the night of his loss to Fabio Wardley at London’s O2 Arena on October 25, 2025. The result triggered a provisional suspension in late November 2025. After Parker supplied evidence that his nutritionist had used cocaine daily in the week before the bout, UKAD concluded the ingestion occurred out-of-competition and was unrelated to sporting performance. The agency lifted the provisional suspension on June 22, 2026, deeming a three-month period of ineligibility already served. Parker is now free to fight again.
Background & Context
Cocaine is prohibited only in-competition under the World Anti-Doping Code. Parker, a 34-year-old New Zealander with a 36-4 record (24 KOs), denied knowingly taking any banned substance and attributed the positive finding to contamination linked to his nutritionist, whom he hired in April 2023.
