Jamaican sprinter Nesta Carter is set to compete for the first time since he was stripped of his Beijing 2008 Olympic gold medal following a retrospective disqualification for doping.
Carter, who failed for banned energy boosting substance methylhexaneamine following re-analysis of frozen samples, is due to take to the track at the Western Relays event in Montego Bay on Saturday (February 11).
He has not participated for 17 months because of injury as well as notification of the positive test, which meant the Jamaican 4x100 metres relay team lost their Olympic gold medal from the Games in the Chinese capital.
The team, which included Carter, Michael Frater, Asafa Powell and Usain Bolt, have all now reportedly returned their medals to the International Olympic Committee (IOC).
Bolt consequently no longer holds a "treble-treble" of 100m, 200m and 4x100m relay victories from the Beijing, London 2012 and Rio 2016 Olympics.
Carter, who ran the first leg in Beijing, has vowed to appeal the decision to the Court of Arbitration for Sport (CAS) and has been cleared to compete pending the result of the case.
The 31-year-old has until February 15 to officially lodge an appeal with the CAS.
He has not been provisionally suspended by the International Association of Athletics Federations (IAAF) and Olivier Gers, chief executive of the worldwide governing body, confirmed to the Jamaica Athletics Administrative Association (JAAA) that he would be free to participate.
According to Reuters, a letter from Gers to JAAA President Warren Blake read: “Having consulted the IAAF Medical and Anti-Doping Department, it appears that Mr. Carter is not currently provisionally suspended.
“He is eligible to compete in athletics competition pending the CAS proceedings.”
It was claimed last month that the entire Jamaican team were considering an appeal, although Bolt was non-committal about whether he would consider contributing financially.
Carter also formed part of the gold medal winning team in London, but it is thought that retests of his sample there has come back negative.
He was also a member of the 4x100m team which won gold medals at the 2011, 2013 and 2015 IAAF World Championships in Daegu, Moscow and Beijing respectively.
