Alexandre Vinokourov's backup sample has confirmed the original finding of a banned blood transfusion, a senior official said Saturday. The person spoke on condition of anonymity because he was not authorized to discuss the case. The Kazakh rider and his Astana team were forced out of the Tour on Tuesday, when it was revealed Vinokourov had failed a doping test. Last Saturday, he tested positive after winning a time trial. On Monday, Vinokourov also won stage 15 - a tough climb in the Pyrenees.
