Heavyweight world champion Tyson Fury, who pulled out of an Oct. 29 rematch with former champion Wladimir Klitschko last week for unspecified reasons, with his promoter only saying he was "medically unfit," has been notified that he tested positive for cocaine.
Klitschko and Fury agreed to have drug testing for their rematch overseen by the Las Vegas-based Voluntary Anti-Doping Association.
England's Fury submitted to a random urine test Sept. 22 in Lancaster, England, and those results came back positive for the substance benzoylecgonine, the central compound found in cocaine and the marker for a positive test for the banned substance.
In a letter from VADA president Dr. Margaret Goodman sent to representatives for Fury, Klitschko, the British Boxing Board of Control and the United States' Association of Boxing Commissions on Thursday night, a copy of which was obtained by ESPN.com, she wrote, "This letter is to advise you that the 'A' sample urine specimen number 4006253 collected from Tyson Fury on September 22, 2016 in Lancaster, England through his participation in the Voluntary Anti-Doping Association (VADA) program has been analyzed for anabolic agents, diuretics, beta-2 agonists, stimulants and drugs of abuse. The results of the analysis are as follows: Adverse. Urine specimen contains benzoylecgonine."
The VADA testing for performance-enhancing drugs is done separately and takes longer, so those results are not yet available.
"Mr. Fury has the right to promptly request analysis of the 'B' sample at his expense," Goodman wrote.
The positive test likely will result in Fury being stripped of his heavyweight world title belts, which he was supposed to defend in a rematch with Ukraine's Klitschko on Oct. 29 at the Manchester Arena in Manchester, England, Fury's hometown.
