Russian curler Alexander Krushelnitsky has been found guilty of doping after testing positive for meldonium.

The Russian Olympian won bronze for curling mixed doubles with his partner and wife Anastasia Bryzgalova in Pyeongchang.

The Court of Arbitration for Sport on Thursday said Krushelnitsky, 25, tested positive for the banned substance meldonium, a drug that can help endurance.

CAS said the duo, who competed in Pyeongchang as part of Olympic Athletes from Russia, had been disqualified from the Winter Games.
