Parker’s positive cocaine test caused by nutritionist, doping body says

Former world heavyweight champion Joseph Parker tested positive for cocaine following his loss to Fabio Wardley in London last October. An investigation by UK Anti-Doping (Ukad) has determined that the presence of the substance was caused by the boxer's nutritionist.

The findings clarify the circumstances surrounding the positive test for the 34-year-old New Zealander. The investigation report identifies the nutritionist as the source of the contamination, attributing the test result to external factors rather than intentional use.
