Russian curler Alexander Krushelnitckii, who won bronze in this year’s mixed doubles competition in South Korea, faces evidence that he cheated is way to third place. On Tuesday, the International Olympic Committee announced that his second urine sample also tested positive for at least one use of the banned performance-enhancing substance meldonium.

Krushelnitckii reportedly told Russian officials that he fears someone at a training camp in Japan spiked his drink with meldonium before he travelled to South Korea.
