Former world heavyweight champion Joseph Parker's nutritionist has been identified as the cause of a positive test for cocaine, according to an investigation report cited by BBC Sport. The positive test was conducted by UK Anti-Doping (Ukad). Parker had claimed that the failed drug test was due to his nutritionist's cocaine use.
The investigation report, as mentioned by BBC Sport, attributes the presence of cocaine in Parker's test to his nutritionist. Another source, Sports News, also reports that Parker claimed the failed drug test was caused by his nutritionist's cocaine use, corroborating the initial claim. However, details on the investigation's methodology and findings are limited in the available sources.
This incident matters as it highlights the potential for unintended doping in sports through indirect means, such as contact with individuals using banned substances. The context and implications of this event are significant for the sports doping control community.
