KINGSTON (Reuters) - Jamaican Olympic relay gold medallist Nesta Carter's "B" sample for the use of a banned stimulant at the 2008 Beijing Games has returned positive, two sources familiar with the case told Reuters on Wednesday.
The Jamaica Olympic Association (JOA) said last Friday in a statement it had received notification from the International Olympic Committee (IOC) that one of its competitors had returned an adverse analytical result but did not name the athlete.
