Russians reeling from doping case

Curler's positive test poses tough questions for IOC

PYEONGCHANG, South Korea - A Russian curler who passed rigorous vetting to attend the Pyeongchang Games was hit by a drug case on Monday, raising questions over the testing program and the move to let Russians compete despite systemic doping.

Alexander Krushelnitsky, who won bronze in the mixed doubles curling with his wife, Anastasia Bryzgalova, was the subject of a new procedure at the Court of Arbitration for Sport's (CAS) anti-doping division.
