KINGSTON, Jamaica (Reuters) Sprinter Sheri-Ann Brooks, one of five Jamaican athletes to test positive for a banned stimulant in June, has been cleared for the world championships due to an 'irregularity' in testing for her second sample.

Brooks, who tested positive for the stimulant methylxanthine along with four other world squad members at the Jamaican national championships, was cleared after a disciplinary hearing on Wednesday, Jamaican anti-doping officials said.
