A cyclist on Lance Armstrong’s U.S. Postal Service team has tested positive for a banned substance in South Africa.
David George, who rode with Armstrong in 1999 and 2000, tested positive for Erythropoietin, according to South Africa’s Institute for Drug-Free Sport said. EPO is a glycoprotein hormone that increases red blood cell production. George failed the test Aug. 29 and is suspended pending an appearance before a doping tribunal, according to an Associated Press report.
“His biological passport indicated suspicious activity and that triggered a targeted test for EPO,” SAIDS chief executive Khalid Galant said. “A subsequent urine test came back positive for the banned EPO drug.”
Armstrong has been banned for life by the International Cycling Union and stripped of his seven Tour de France titles after the United States Anti-Doping Agency determined that he played a significant role in cycling’s doping scandal.
