Kazakh rider Alexandre Vinokourov's B sample confirmed that he had been blood doping, sources told AFP on Saturday.
Vinokourov was thrown out of the Tour de France on Tuesday when it was revealed that an 'A' sample taken from the Astana team rider after his victory in the time trial on the 13th stage revealed the presence of "two distinct blood populations".
That suggested Vinokourov had injected the blood from a compatible donor to boost his performance in the race against the clock. - Sapa-AFP
