Berlin - German cyclist Stefan Schumacher was identified on Wednesday as one of the six athletes from the Beijing Olympic Games who has tested positive for banned blood-booster EPO CERA.
"The German Cycling Federation (BDR) have passed documents about a failed doping test on to the sportsman Stefan Schumacher," said the BDR in a statement.
"It is now up to him whether he requires the opening of the B sample or not."
The International Olympic Committee (IOC) announced on Tuesday that six sportsmen had tested positive for CERA, a new strain of the illegal blood-booster Erythropoietin (EPO).
Italian cyclist Davide Rebellin, who won Olympic silver in the men's road race, and 1500m runner Rashid Ramzi from Bahrain, who won gold in Beijing, have also been confirmed as being among the six caught after their samples were retested.
Schumacher first tested positive for EPO CERA in October 2008 after a sample he gave during the Tour de France was retested and in February he was banned by the UCI, cycling's governing body, for two years.
Schumacher and Rebellin rode together for the defunct German cycling team Gerolsteiner in 2008.
