Jamaican sprinter's 'A' sample shows adverse finding for banned drug

There are reports that a Jamaican sprinter has returned an adverse analytical finding of a banned substance.

According to information reaching The Gleaner, the athlete, who was expected to feature at the upcoming IAAF World Athletics Championships in Doha, Qatar, has been informed that their A sample, which was taken at the National Senior Championships in June, has returned a positive result for a banned diuretic. 

The substance is believed to have been contained in a popular cold and flu medication.
