Tyson Fury is likely to escape punishment from UK Anti-Doping should a case against him be re-opened. 

It's been reported that the WBC heavyweight world champion formally relinquished his British Boxing Board of Control (BBBoC) license prior to his victory over Deontay Wilder.

Fury - along with cousin Hughie - had drug tests show the higher-than-permitted levels of nandrolone. Those nandrolone levels were spiked as a result of the Furys eating uncastrated wild boar.

They each received two-year back-dated bans and have obviously both resumed boxing since then.

However, the farmer that provided testimony about the boar has since recanted in an article with the Daily Mail.

Martin Carefoot claims he was offered £25,000 to provide alibis for Tyson and Hughie Fury, but now says he has never farmed wild boar - castrated or otherwise.

Should a case be reopened against the Furys by UKAD they could face added charges of attempting to tamper with witnesses.

However, such bans would only be enforced if Tyson Fury specifically was under UKAD's jurisdiction.

According to BoxingScene, that no longer appears to be the case.

Tyson Fury last boxed in the UK with his August 2018 victory over Francesco Pianeta at Windsor Park, and is required to renew his licence every year.

However, BoxingScene claim that the WBC heavyweight champion has not only let the licence lapse, but prior to the win over Wilder in Las Vegas in February he wrote to the BBBoC to formally relinquish the licence.

Were Fury still in receipt of a UK licence, any punishments that would come from a potentially re-opened UKAD case would have to be enforced with the four main boxing governing bodies given the BBBoC's relationship with UKAD.

However, without a UK licence Fury is beyond BBBoC's jurisdiction and other bodies are under no obligation to honour what is now a five-year old doping charge.

Fury's next outing is set to be a third bout with Wilder either later this year, or early in 2021.
