Jamaican sprinter appeals ruling

Jamaican sprinter Nesta Carter has appealed to the Court of Arbitration for Sports (CAS) against his disqualification in his country’s 4 x 100 meters relay team, including Usain Bolt, who was stripped of their Beijing 2008 Olympic gold medals.

He was disqualified from the race last month after he failed a drugs test for a banned energy-boosting substance methylhexaneamine, following re-analysis of frozen samples.

The team, which included Carter, Michael Frater, Asafa Powell and Bolt, have since turned in all their medals to the International Olympic Committee (IOC).

Bolt no longer holds a “treble-treble” of 100m, 200m, and 4 x l00m relay victories from the Beijing, London 2012 and Rio 2016 Olympics.

Carter, who ran the first leg in Beijing, how vowed to appeal the decision to CAS and had until recently to do so.
