Rebellin won his silver medal on his 37th birthday
Davide Rebellin has been stripped of his Olympic cycling road race silver medal after a positive dope test.
The Italian tested positive for Cera, an advanced version of endurance-enhancing substance EPO, after coming second behind Spain's Samuel Sanchez.
Italy's Olympic Committee (CONI) said the International Olympic Committee (IOC) had disqualified the 38-year-old.
Fabian Cancellara and Alexander Kolobnev, who came third and fourth, could now be promoted as a result.
When the initial test results were made public in April, Rebellin denied any wrong-doing, telling Italian newspaper La Stampa: "I don't know what may have happened. It is certainly a mistake. It is impossible that I tested positive."
He now faces a CONI disciplinary hearing and will also pay them back prize money of around £67,000.
The IOC tested 948 samples from Beijing after new tests for Cera and insulin became available after the Olympics.
