Insufficient evidence has been found against all but one of 96 Russian athletes reviewed so far by the World Anti-Doping Agency (WADA), according to reports.
WADA has been investigating individual athletes implicated in the doping scandal which has embroiled Russia.
None of the 96 athletes – the first to be reviewed by WADA – have been named.
insidethegames writes, however, that these cases relate largely to athletes already examined and cleared by different International Federations.
“The available evidence was insufficient to support the assertion of an anti-doping rule violation against these 95 athletes,” said WADA director general Olivier Niggli in a leaked report seen by The New York Times.
The newspaper has also reported that WADA officials did not receive testimony from Grigory Rodchenkov, the former head of the Moscow Laboratory who turned whistleblower.
His allegations led to investigations into Russian doping as well as two editions of the highly-critical McLaren Report.
Rodchenkov has been forced to leave Russia and is now in the United States.
His lawyer, Jim Walden, wrote to the New York Times to claim that his client would have cooperated with WADA.
