Team Astana quit the Tour de France on Tuesday after star rider Alexandre Vinokourov tested positive for a banned blood transfusion, a team spokeswoman said.
The Kazakh rider, a pre-race favorite, has won two stages on this year’s Tour. Vinokourov also won Monday’s 15th stage and is 23rd in the overall race standings, but he has all but fallen out of contention after losing 28 minutes, 50 seconds to Tour leader Michael Rasmussen in Sunday’s stage.
According to French sports daily L’Equipe, the analysis of Vinokourov’s test was conducted by the Chatenay-Malabry lab on the outskirts of Paris. It said two distinctive types of red blood cells were found in the A sample and showed that Vinokourov received a blood transfusion from a compatible donor shortly before the time trial.
With a guy of his stature and class, in cycling’s current situation, we might as well pack our bags and go home.
