U.K. Anti-Doping has lifted a provisional suspension on RING, WBA and WBO heavyweight champion Tyson Fury while it completes an investigation.

Fury was suspended  after what was reported to be a positive test for performance enhancing drugs. Fury denied taking PEDs and his “B” sample reportedly came back clean.

The following is the sequence of events that led to the most recent decision.

June 26, 2016 – The Sunday Mirror, a U.K. tabloid, reports that trace amounts of the banned substance nandrolone were detected in Fury’s urine sample in UKAD testing, dating back to February 2015. The same report states that Fury’s cousin, heavyweight contender Hughie, had also tested positive for the anabolic steroid. The Fury camp denies all allegations.

July 29, 2016 – Fury’s legal team says his “B” sample had come back negative, as did a blood test conducted around the same time, according to a report in The Sun. The report states that UKAD informed Team Fury that a contaminated dietary supplement was the most likely cause for the positive result on the “A” sample.

Aug. 2, 2016 – Tyson Fury’s legal representation issues a statement. “The two boxers strenuously deny taking any performance-enhancing drugs,” said lawyer Lewis Power. “However, during the last five weeks, leaks about these charges have appeared in the press and both boxers have been the targets of continual abusive language on Twitter.” Team Fury states it will sue for damages.

Aug. 3, 2016 – Tyson Fury’s trainer and uncle, Peter, confirmed via Twitter that the provisional sanctions, issued by UKAD, had been lifted: “To all our fans. (The) UKAD suspension (is) lifted. (Tyson and Hughie) can and will be fighting with (the) full go ahead from (the) tribunal.”

A spokeswoman for UKAD told the Press Association: “U.K. Anti-Doping will not discuss or disclose details of cases until due legal process has been completed and an anti-doping rule violation has deemed to have been committed, at which point information will be published on our website. This is to ensure that the rights and privacy of everyone involved are respected and protected, and to ensure cases are not unnecessarily prejudiced.”

Tyson Fury’s rematch with Wladimir Klitschko is scheduled to take place on Oct. 29 in Manchester, England, with Hughie Fury set to appear on the undercard. Tyson, who is still recovering from an ankle injury, outpointed the Ukrainian legend to win his titles last November in Dusseldorf.
