Frank Schleck will miss the 2013 Tour de France after he was handed a one-year backdated ban for failing a doping test during last year's race, the Luxembourg Anti-Doping Agency said on Wednesday.

Schleck, third overall in the 2011 Tour, tested positive for the diuretic Xipamide following the 13th stage.

ALAD representative Raymond Mousty told a news conference that the ban started from the day Schleck failed the test on July 14, 2012.
