PARIS -- German cyclist Stefan Schumacher tested positive for a banned substance during the Tour de France, his team said Monday.
Schumacher, who won both individual time trials at the Tour and held the race lead for two days, tested positive for CERA, an advanced version of the blood-boosting hormone EPO.
"I have received a confirmation from Christian Prudhomme that Stefan Schumacher was tested positive for CERA" during this year's Tour de France, said Gerolsteiner team manager Hans-Michael Holczer, adding the rider was immediately suspended from the team.
Prudhomme is the Tour de France's race director.
The French anti-doping lab has been retesting samples from the Tour to look for traces of CERA.
