Earlier in the day, International Ice Hockey Federation (IIHF) President René Fasel had revealed there had been one positive test in the KHL but that the level had been below the threshold set by the World Anti-Doping Agency (WADA) and no further action had been taken.

"I have no information about meldonium in KHL," Tretiak told the Russian news agency TASS.

"They say that there are no problems."

WADA had ruled last month that if below one microgram of the heart medication, only added to the prohibited list on January 1, was detected in a test before March 1, a no fault or negligence verdict could be reached after they admitted it was unclear how long the drug stayed in an athletes system. 

Earlier this year several members of the the Russian under-18 ice hockey team were suspended following a glut of positive tests for meldonium.

A decision on whether they will face further action still has to be taken. 

Fasel told insidethegames earlier this month that the IIHF cannot “suddenly suspend a young 18-year-old with no evidence it [meldonium] is performance-enhancing when they maybe took it before [it was banned].”
