US cyclist Tyler Hamilton stripped of Athens gold for doping

American cyclist Tyler Hamilton has been stripped of the gold medal he won at the 2004 Athens Olympics.

Hamilton was banned for blood-doping in 2005 but only admitted taking performance-enhancing drugs last year.

He was initially allowed to keep his Olympic time trial gold because the blood sample he gave in Athens was destroyed but he has now been stripped of gold following his admission.

Russian rider Ekimov Viatcheslav Ekimov will now receive the gold medal.

American Bobby Julich will be moved up from bronze to silver, and Michael Rogers of Australia from fourth to bronze.

The International Olympic Committee (IOC) examined documents from the US Anti-Doping Agency before deciding to reallocate the medals.

IOC spokesman Mark Adams said Hamilton had been notified on Friday that he has been disqualified from his victory in the road race time trial.
