Kingston: Former 100 metres world record holder Asafa Powell was banned for 18 months by a Jamaican anti-doping disciplinary panel on Thursday after he tested positive for a banned substance last year.
The Jamaican sprinter, 31, tested positive for the stimulant oxilophrine at last year`s national championships and the ban has been backdated to June 21 2013 - the day he provided the sample. His ban will end on Dec 20.
The chairman of the three-member disciplinary panel, Lennox Gayle, said: "The panel arrived at a unanimous decision, and it is a decision that in all the circumstances Mr. Powell was found to be negligent and that he was at fault, especially in light of the fact he (is) an elite athlete.
"It is our decision that the period of ineligibility will be 18 months commencing from the date of the sample collection ... the period will expire on the 20th of December 2014."
Powell was not at the hearing but his lead attorney, Kwame Gordon, expressed disappointment at the length of the ban and said his client would appeal to the Court of Arbitration for Sport.
Powell`s sanction comes two days after his former training partner Sherone Simpson received an 18-month suspension from the same panel for the same substance.
Another Jamaican, Olympic discus thrower Allison Randall, was also handed a two-year ban for using the prohibited diuretic hydrochlorothiazide on Tuesday.
Powell, who missed last year`s world championships as a result of his failed test, had testified in January that Canadian physical trainer Chris Xuereb provided him with nine supplements, including Epiphany D1.
His legal team had presented three different laboratory reports that Epiphany D1 contained the stimulant oxilofrine.
However, the two-time 100m world championship bronze medallist told the hearing that he had failed to list them because he could not remember their names.
Xuereb denied providing performance enhancing drugs and said the sprinters should take responsibility for their failed dope tests.
IAAF spokesman Chris Turner declined to comment on Powell`s punishment, saying only: "This is a legal process following IAAF rules which are in accordance with those of WADA (the World Anti-Doping Agency), and the IAAF does not comment until cases are closed."
Turner added: "This case concerns an international athlete and the full, reasoned decision of the member federation has to be sent to the IAAF and considered by the doping review board."
