Vincenzo Nibali's Astana under review after third positive test

Astana rider Maxim Iglinskiy tested positive for EPO in August

Tour de France winner Vincenzo Nibali's Astana team will have its WorldTour elite status reviewed after a third rider failed a doping test in 2014.

Brothers Maxim and Valentin Iglinskiy tested positive for EPO, while llya Davidenok was this week notified of an adverse finding for anabolic steroids.

Maxim was in the nine-strong Astana squad that helped Nibali win the Tour.

Now the International Cycling Union's (UCI) licence commission will review Astana's anti-doping policies.

Last week, the UCI said the team could have "conditions attached to their licence".

Astana's Kazakh boss Alexander Vinokourov completed a two-year drugs ban in 2009 but returned to win the road race at the London Olympics in 2012.

Davidenok, 22, failed a test at August's Tour de l'Avenir, the junior Tour de France, where he won a stage. He was also eighth in the Under-23 World Championships a month later.

The Kazakh rider has the right to request analysis of his 'B' sample but has been provisionally suspended.
