In the wake of a damning report on Russian doping, the World Anti-Doping Agency (WADA) has suspended the accreditation of Moscow's drug-testing laboratory.
According to various media reports, WADA said it acted on the recommendation made by the intendant commission to close the Russian laboratory.
This means that, with immediate effect, the Moscow lab will not be allowed to test any blood or urine samples. Any testing that was to be done by the Moscow lab will now be done by alternative WADA-accredited labs.
The Moscow lab has 21 days to appeal the decision to the Court of Arbitration for Sport. WADA plan on forming a disciplinary committee that will review the case.
Earlier in the day, the former president of the Russian athletics federation, Valentin Balakhnichev, said that he was prepared to go to court to clear his name.
Balakhnichev resigned in February over reports that he attempted to extort money from athletes accused of doping.
He told Russia's Tass news agency that he planned on going to the Court of Arbitration for Sport "otherwise we won't get to the bottom of this situation."
The initial report did not name Balakhnichev on the list of Russian officials and coaching staff recommended for lifetime bans.
