>> A Russian medalist is accused of doping at the PyeongChang Winter Olympics. If found to be true, that's likely to deal a blow to Russia's efforts to emerge from a drug cheating scandal. Aleksandr Krushelnitckii won bronze alongside his wife in mixed doubles curling. He's now suspected of having tested positive for meldonium, a source at the game said on Sunday.
The drug increases blood flow, which enhances exercise capacity. Krushelnitckii has not commented on the allegations, and a violation can only be confirmed by analysis of a B sample. The couple's rivals, Norway, would take the bronze if it's proven. Russia has been accused of running a state-backed systematic doping program for years.
Moscow denies the allegation. But as a result, its athletes are competing at PyeongChang as neutral Olympic athletes from Russia.
