>> A Russian bobsledder has been disqualified from the Winter Olympics after testing positive for a banned drug. That's according to the Court of Arbitration for Sport, which said Nadezhda Sergeeva tested positive for a heart drug used to treat angina. A Russian official says that the dose was so small she may not have consumed a pill, but says she may have been sprayed or smelled something or licked something.
Sergeeva finished 12th with Anastasia Kocherzhova in the women's bobsled competition on Wednesday. Her disqualification comes on the heels of Russian curler Alexander Krushelnitsky agreeing to hand back his mixed team bronze medal after testing positive for maldonium. And it comes as the International Olympic Committee's executive board was meeting to discuss whether to lift the suspension of Russia's Olympic Committee, and possibly allow them to march with the Russian flag at Sunday's closing ceremony.
If the suspension is not lifted, the athletes will march as they did for the opening ceremony, behind the Olympic flag in neutral uniforms.
