Olympian Nesta Carter has filed an appeal with the Court of Arbitration for Sport (CAS) after being stripped of his Beijing 2008 sprint relay gold medal.
With the 21 day appeal period set to expire on Wednesday, RJR Sports has learnt that the sprinter's legal team has lodged an appeal with the Switzerland - based court.
The sprinter was stripped of the Olympic gold medal after returning an adverse analytical finding for the banned stimulant methylhexaneamine following re-testing of his stored 2008 sample.
The action also resulted in Usain Bolt's Olympic gold medal haul being reduced to eight with Asafa Powell, Michael Frater and Dwight Thomas also having to return their gold medals.
Last week the IAAF confirmed that Carter had not been suspended and the Jamaica Athletics Administrative Association (JAAA) cleared the sprinter to resume competition pending his appeal to CAS.
Carter opened his season last Saturday, anchoring his MVP Track Club to second place in the men's sprint relay at the Milo Western Relays.
