NEW YORK -- Three-time Tour de France champion Alberto Contador reportedly tested positive for a specific type of chemical that could point to him getting a blood transfusion to boost endurance.
The New York Times reports Contador, who tested positive for clenbuterol during cycling's most prestigious event this past July, tested positive for a chemical called a plasticizer. That is found in plastic IV bags, which could suggest that he had a blood transfusion. The newspaper says Contador's urine samples revealed levels of that chemical eight times higher than the minimum amount that signifies doping.
Contador, the two-time reigning Tour de France winner, claims his testing positive for clenbuterol was a case of food contamination caused by tainted beef from Spain.
