Russia’s national anti-doping agency RUSADA says that Kirill Sveshnikov, who last year won a medal at last year’s UCI Track Cycling World Championships, has been provisionally suspended after failing a doping control.

Sveshnikov won bronze in Minsk 12 months ago in the points race, won by Great Britain’s Simon Yates, with Spain’s Eloy Teruel second.

The A sample that tested positive for an unnamed substance was taken in January at the Russian national track championships.

RUSADA says that Sveshnikov, aged 22 has been informed of the possible anti-doping violation and of his rights, which under current rules would include that he can request a test of his B sample.

In the meantime, RUSADA says he is suspended from all competitions and training camps.

According to a tweet from the French website Velochrono, Sveshnikov is the eighth Russian cyclist to have tested positive in an anti-doping control within the past 12 months.
