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 denied wrongdoing, saying the failed test was a surprise, according to Spanish news agency EFE.
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.
Two years later, Sanchez finished fourth in the Tour de France but was upgraded to second behind Schleck due to doping bans for original winner Alberto Contador and third-place Denis Menchov.
Sanchez also took the polka-dot jersey for best climber at the 2011 Tour and finished second and third at the Vuelta in 2009 and 2007, respectively.
