Jamaican sprinter Nesta Carter has filed an appeal of his recent doping confirmation with the Court of Arbitration for Sport (CAS), the president of his track club confirmed on Thursday.
Bruce James, president of the MVP track club, said the 31-year-old sprinter will push his efforts to CAS to overturn the January 25 sanction imposed by the International Olympic Committee (IOC) after a retest of his sample from the 2008 Beijing Olympics.
News agency, Reuters, is reporting that Jamaican Olympic relay gold medalist Nesta Carter's "B" sample for the use of a banned stimulant at the 2008 Beijing Games has returned positive.
This comes days after it was revealed that Carter's "A" sample had also been tested positive, which could see Jamaica being stripped of the 2008 4x100 metre gold medal.
Trinidad and Tobago finished second in that event.
Trinidad and Tobago's 2008 Olympic 4x100 metre team could be awarded the gold medal for the event, after placing second at the Bird Nest Stadium in Beijing.
The Gleaner Newspaper in Jamaica is now reporting that Jamaican Nesta Carter, who was part of Jamaica's gold medal team, has been identified as one of 32 athletes who failed a retrospective drugs test.
That now puts Jamaica's gold medal in jeopardy.
The Gleaner said a retest of Carter`s `A` sample from the Beijing Games had found traces of the banned stimulant Methylexaneamine.
