Samuel Sanchez, a 2008 Olympic champion and 2010 Tour de France runner-up, was provisionally suspended after testing positive for a banned growth hormone on Aug. 9.
Sanchez, a 39-year-old Spaniard, was due to race the Vuelta a España starting Saturday but is now out indefinitely until the conclusion of his case. That may include the testing of his B sample.
Sanchez won the road race on the first day of the Beijing Games in a five-man sprint that also included Swiss Fabian Cancellara, who would win the time trial in 2008 and 2016, and Luxembourg’s Andy Schleck.
