With less than three months to go before the 2014 Sochi Olympics, the principal drug-testing laboratory in Russia could lose its international accreditation.
The World Anti-Doping Agency is investigating the Moscow facility -- which handled testing for the recent world track and field championships -- to be sure it is compliant with agency standards.
Arne Ljungqvist, the medical commission chairman for the International Olympic Committee, told the Associated Press that he expects to receive the investigation's findings soon.
"We are all aware of the problems," said Ljungqvist, who is also a WADA official. "Otherwise, the disciplinary procedure would not take place."
