Parker's positive test for cocaine caused by nutritionist

Former world heavyweight champion Joseph Parker tested positive for cocaine during a UK Anti-Doping (UKAD) test conducted last year. An investigation into the incident has officially attributed the presence of the substance to his nutritionist.

The findings confirm that the positive result was caused by the actions of the nutritionist rather than intentional use by the athlete. The investigation concludes the matter regarding the origin of the traces found in the testing sample.
