Parker has always denied knowingly taking any banned substances and United Kingdom Anti-Doping (UKAD) said the nutritionist he employed ahead of his fight with Wardley was a “regular user of cocaine”.
“New Zealand professional boxer Joseph Parker has served a three-month ban from all World Anti-Doping Code-compliant sport following an anti-doping rule violation (ADRV) for the presence of a prohibited substance,” a UKAD statement said on Thursday.
“At the time of this announcement, Mr Parker is free to participate in sport.”
The statement added: “On ۶ March ۲۰۲۶, Mr Parker provided UKAD with evidence claiming that the adverse analytical finding was the result of his exposure to cocaine used by the nutritionist he had employed in preparation for the bout on ۲۵ October ۲۰۲۵.
“The nutritionist stated that he was a regular user of cocaine and had used cocaine daily in the week leading up to the bout.”
Parker was tested by the Voluntary Anti-Doping Association (Vada) on October ۲۵.
On the same day, he was also beaten by Briton Wardley at London’s O۲ Arena.
Parker also failed a UKAD test in the early hours of October ۲۶.
UKAD added it had found in June that Parker’s cocaine ingestion had occurred out of competition and therefore was “in a context unrelated to sport performance”, therefore lifting his previous suspension.
Parker’s professional record stands at ۳۶ wins and four defeats.
He was WBO heavyweight champion from ۲۰۱۶ to ۲۰۱۸ before losing the title to Britain’s Anthony Joshua in Cardiff.
UKAD’s statement came a day after Parker himself announced his ban had been lifted.
“I’m pleased to confirm my provisional suspension is lifted and I’ll be back in the ring soon,” he said.
Parker suffered an ۱۱th-round stoppage defeat by Wardley and lost his status as WBO mandatory challenger to then undisputed heavyweight champion Oleksandr Usyk.
