CAPE TOWN, South Africa (AP) — South African cyclist David George, a former teammate of Lance Armstrong, has tested positive for blood-boosting EPO.

South Africa’s Institute for Drug-Free Sport says George, who cycled with Armstrong on the U.S. Postal Service team in 1999 and 2000, failed a doping test on Aug. 29.

SAIDS says George has been provisionally suspended and faces a doping tribunal.

SAIDS chief executive Khalid Galant says, “his biological passport indicated suspicious activity and that triggered a targeted test for EPO.”

Last month, Armstrong was banned for life by the International Cycling Union and stripped of his seven Tour de France titles because of his role in a doping scandal, which was outlined in a report by the U.S. Anti-doping Agency.

George is also a two-time Commonwealth Games medalist.
