>> A second Russian athlete has tested positive for a performance enhancing drug at the Winter Olympics. This time it's Bobsledder Nadezhda Sergeeva for a banned heart drug. The Russian Bobsled Federation said the team's medical staff did not prescribe the drug to the athlete. Adding that they understand the findings could have an impact on the fate of the whole team.
Russia's sporting reputation has already been dealt a blow in PyeongChang after curling medalist, Aleksandr Krushelnitckii, tested positive for meldonium. The case shocked Russian athletes and raised questions about whether it was intentional. The jury's out on the merits of an endurance enhancing drug in curling. But earlier this week he agreed to hand back his team bronze medal.
The incidents could shatter Russia's hopes of redemption and being allowed to march under the Russian flag at Sunday's closing ceremony. Russian athletes have been competing as neutrals after the country was banned amid allegations of a state-sponsored doping system. Moscow denies the claims and had hoped a positive Winter Olympics could put it behind them.
But it's athletes performance in Pyongchang could be remembered for the wrong types of positives.
