Olympics-Doping case launched against Russian athlete - tribunal

PYEONGCHANG, South Korea, Feb 19 (Reuters) - The Court of Arbitration for Sport has launched a doping procedure against Russian Olympic medallist Alexander Krushelnitsky, the court said in a statement on Monday.

The court said no hearing date had been fixed yet and no further information would be provided for the moment.

Alexander Krushelnitsky, who competes in curling, is suspected of testing positive for meldonium, a banned substance that improves exercise capacity. Krushelnitsky, who won bronze with his wife in mixed-doubles curling in Pyeongchang, has not responded to a request for comment.

Russia's curling federation has also launched an "emergency commission" to investigate the doping case, federation president Dmitry Svishchev told Reuters. (Reporting by Gabrielle Tetrault-Farber Karolos Grohmann; Editing by Mark Bendeich)
