Astana rider Maxim Iglinskiy, who in July helped Vincenzo Nibali win the Tour de France, is provisionally suspended after testing positive for EPO, a UCI document reveals. The news comes just three weeks after the Kazakh team sacked his younger brother, Valentin, after he too was provisionally suspended following a positive test for EPO and admitted having used the banned substance.

Blogger the Inner Ring this evening tweeted a link to the UCI’s list of riders who are provisionally suspended. The UCI’s current policy is not to issue individual press releases when a rider receives such a suspension.

However, the document does reveal that the test that has resulted in the elder Iglinskiy’s provisional suspension took place on 1 August – less than a week after the Tour de France ended, and the day before he took part in the Clasica Ciclistic di San Sebastian.

Meanwhile the positive test which led to his younger sibling admitting doping happened a week and a half later on 11 August.

Of the Iglinskiy brothers, Maxim has the much higher profile. In 2012, the Kazakh beat Nibali, then riding for Liquigas-Cannondale, to win Liege-Bastogne-Liege.

Astana is a member of the Movement for Credible Cycling (MPCC), under whose rules teams signed up to it should suspend themselves from racing where two riders have tested positive in the preceding 12 months, starting eight days from when they became aware of the second positive test.

As the Inner Ring points out, if Astana comply with that rule, they will have to withdraw from the most prestigious race in their home country, the one-day Tour of Almaty, which is held on Friday. The inaugural edition last year was won by none other than Maxim Iglinskiy.

Under another rule the team, whose general manager is Alexandre Vinokourov, must explain itself at the next MPCC meeting for the positive tests.
