The UCI has confirmed the positive anti-doping test carried out earlier in the Tour on Alexander Kolobnev after Stage 5 of the race, from Carhaix to Frehel.
The organisation said today in a press statement that the analysis of the Russian Katusha rider’s B sample carried out yesterday confirmed the result of the initial adverse analytical finding by the Anti-doping laboratory of Châtenay-Malabry following the analysis of the A sample.
Therefore, the statement says, in accordance with the Anti-doping rules, the UCI will request the Russian Federation to open a disciplinary procedure against the 30-year old rider.
When the result of the A sample test was announced Kolobnev voluntarily suspended himself from the Tour. His team issued a statement at the time saying: "Internal rules in Team Katusha say that the rider, if the B-sample also tests positive, he will be fired and will have to pay five times his salary as a fine."
Some reports suggest that fine will be in the order of £1.75m.
Kolobnev tested positive for the banned substance Hydrochlorothiazide, a diuretic that can be used as a masking agent for other prohibited substances.
