Joseph Parker Cleared to Return After Three-Month Cocaine Ban

KUALA LUMPUR, AUGUST 2026 — Former world heavyweight champion Joseph Parker is free to return to competition after serving a three-month suspension for an anti-doping rule violation involving cocaine.

United Kingdom Anti-Doping confirmed that the 34-year-old New Zealand boxer had completed the ban and was eligible to participate in sport again.

Parker tested positive for cocaine around the time of his shock defeat by British heavyweight Fabio Wardley at London’s O2 Arena on October 25, 2025.

He was tested by the Voluntary Anti-Doping Association on the day of the fight before failing a UK Anti-Doping test during the early hours of October 26.

Parker consistently denied knowingly taking any prohibited substance.

On March 6, 2026, he submitted evidence arguing that the adverse finding resulted from exposure to cocaine used by a nutritionist he had employed while preparing for the Wardley bout.

According to UK Anti-Doping, the nutritionist acknowledged being a regular cocaine user and said he had consumed the drug daily during the week leading up to the fight.

The governing body later accepted that Parker’s ingestion occurred outside competition and in circumstances unrelated to improving sporting performance.

That finding allowed Parker’s earlier provisional suspension to be lifted.

UK Anti-Doping said he had served a three-month ban from all sport governed by the World Anti-Doping Code and was free to compete at the time of the announcement.

Parker welcomed the decision and confirmed that he intended to return to the ring soon.

The ruling ends months of uncertainty surrounding his boxing career following the positive test and his defeat by Wardley.

Wardley stopped Parker in the 11th round of their heavyweight contest at the O2 Arena.

The loss also cost Parker his position as the World Boxing Organization’s mandatory challenger to Oleksandr Usyk, who was the undisputed heavyweight champion at the time.

Parker’s professional record currently stands at 36 victories and four defeats.

He previously held the WBO heavyweight title from 2016 until 2018, when he lost the championship to Britain’s Anthony Joshua in Cardiff.

The decision means Parker may now resume training and pursue future heavyweight contests without an active anti-doping suspension.

However, the case also highlights the responsibilities placed on professional athletes regarding the conduct of members of their support teams and the risks of unintended exposure to prohibited substances.

The World Anti-Doping Code generally holds athletes responsible for substances found in their bodies, even when ingestion is claimed to be accidental.

In Parker’s case, the accepted evidence and the conclusion that the exposure was unrelated to sporting performance resulted in a comparatively short suspension.

Attention will now turn to Parker’s next opponent and whether he can rebuild his position within the heavyweight division after losing his mandatory challenger status.
