Kingston (Jamaica), April 11:
Jamaica’s former world 100m record holder Asafa Powell has been slapped an 18-month ban for failing a dope test.
Powell described the decision “unfair and unjust”, and said a legal supplement he took, Epiphany D1, was contaminated.
He plans to appeal to the Court of Arbitration for Sport.
Fellow sprinter Sharone Simpson was also banned Tuesday by the Jamaican anti-doping disciplinary panel.
Simpson, an Olympic 4x100m relay gold and silver medallist, is a training partner of Powell and took the same substance at the same meet.
Another Jamaican, Olympic discus thrower Allison Randall, was also handed a two-year ban Tuesday for using a prohibited diuretic.
Powell and Simpson, who provided their samples on June 21, 2013, will miss the Commonwealth Games in Glasgow in July.
The three-member disciplinary panel that ruled on Powell said he had been “negligent”.
IAAF spokesman Chris Turner said there would be no comment from athletics’ world governing body while the case was still open.
Powell, the biggest name in Jamaican sprinting before the rise of double world and Olympic champion Usain Bolt, missed last year’s World Championships as a result of his failed test.
In January, he testified that Canadian physical trainer Chris Xuereb provided him with nine supplements, including Epiphany D1.
Xuereb has denied providing performance-enhancing drugs.
Prior to the verdict and in the wake of the Veronica Campbell-Brown case, Powell’s coach, Stephen Francis, called on the Jamaican Prime Minister to disband the country’s anti-doping organisation and sub-contract the testing procedures to a credible overseas testing agency.
Earlier this year, the Court of Arbitration for Sport cleared Campbell-Brown, a two-time Olympic 200m champion, of a doping violation.
