Nesta Carter

Miami: Embattled Jamaican sprinter Nesta Carter is allowed to compete pending the outcome of his appeal over retroactively testing positive for the prohibited substance methylhexaneamine, The Gleaner newspaper reported Tuesday.

Usain Bolt’s feat of winning Olympic gold in the 100, 200 and 4x100m relay at three consecutive Games was foiled last month when Carter’s positive re-test disqualified the Jamaican 4x100m relay from gold at the 2008 Beijing Olympics.
