Normally rest days on the Tour de France are just that - restful. But ESPN is reporting Frank Schleck of the RadioShack team will withdraw from the Tour de France after testing positive for a banned substance on Tuesday.
Schleck tested positive for the diuretic Xipamide, which the team said is not in any medicine used by the squad and it was unclear why it was detected in Schleck.
This is an ongoing reminder of how drugs persist in cycling's top event, with Schleck just another high-profile cyclist to test positive. He finished third in last year's Tour de France and was currently in 12th place overall at 9 minutes and 45 seconds behind leader Bradley Wiggins.
Schleck was notified of the positive test and went to the Pau police station on his own accord to cooperate with authorities. He has the right to request a test on his B sample within the next four days.
This is the second doping case to come from the tour this year. French rider Remy Di Gregorio was arrested on July 10th as part of a Marseille doping inquiry.
