PYEONGCHANG, South Korea  _ US biathlete Lowell Bailey says a second failed drug test by a Russian athlete at the Pyeongchang Games shows that the country still "hasn't gotten the message" on doping.

"After all that's happened with the IOC, they're clearly still willing to push the limits and break the rules and cheat. And that's not part of the Olympics," Bailey said after the Russian Bobsled Federation announced that a drug-test sample that pilot Nadezhda Sergeeva gave was positive.

Speaking after competing in the men's 4 x 7.5-kilometer relay Friday, where the US team placed sixth, Bailey called for stronger deterrents against doping.

"If we don't install those deterrents, we are going to be seeing this at the next Olympics, and the next Olympics, because there's just not enough of a reason for Russia to not cheat," he said.

"They are going to continue to cheat until something comes down that's strong enough, punishment, that they'll say, 'OK, enough is enough.'"  

Russia's delegation at the games said the substance found was trimetazdine, a medication used for angina sufferers that is listed by the World Anti-Doping Agency as a banned substance affecting the metabolism.

News of the positive came a day before the International Olympic Committee's executive board is to decide whether to reinstate the country for Sunday's closing ceremony.

The Russian team was barred from the Olympics in December for doping at the Sochi Games, but the IOC invited 168 athletes from the country to compete under the Olympic flag.
