Contador's claim rejected by WADAAlberto Contador‘s claim that contaminated meat was responsible for his positive doping test has been rejected by the World Anti-doping Agency (WADA), according to a Spanish newspaper.

Contador, the Tour de France champion, was provisionally suspended after a positive test for clenbuterol, a banned weight loss and muscle building drug.

Contador, who also won the Tour de France in 2007 and 2009, has threatened to quit the sport if suspended for two years.
