Contador has always claimed the positive result was from contaminated beef he eat during the race.

MADRID — Former Tour de France winners say Alberto Contador's two-year ban for doping is a blow to cycling.

Five-time Tour champion Eddy Merckx tells The Associated Press "it's like someone wants to kill cycling."

Contador was stripped of his 2010 Tour title on Monday when the Court of Arbitration for Sport rejected his claim that his positive doping test was caused by eating contaminated meat. The Spanish cyclist joined Floyd Landis as the only other rider to lose a Tour de France title.

Oscar Perreiro, who was elevated to 2006 champion after Landis was stripped, calls the verdict "disgraceful" and claims Contador "is innocent."
