The German cycling team Gerolsteiner has withdrawn from racing after Austrian rider Bernhard Kohl failed a drugs test.

Kohl, winner of the mountains jersey at this year's Tour de France and third overall, tested positive for the latest generation of the banned blood booster EPO (erythropoietin), named CERA.

Teammate Stefan Schumacher of Germany also tested positive for CERA.

Gerolsteiner's sponsorship of the team was set to come to an end at the end of this year, but the German mineral water company has decided to withdraw from the peloton effective immediately, skipping this weekend's Giro di Lombardia, the final one-day classic of the season.
