A Russian athlete is suspected of breaching doping rules at the PyeongChang Winter Olympic Games.

Russian curlers said that a coach on their team told them late Sunday (South Korean time) that mixed doubles bronze medalist Alexander Krushelnitsky tested positive for meldonium, a substance banned in 2024.

Russian Curling Federation president Dmitry Svishchev would not confirm the name of the athlete.

The International Olympics Committee (IOC) said on Monday that a second sample from the athlete had been taken and results would be available in 24 hours.

If confirmed positive by the second test, the incident could keep Russia's team from being reinstated and marching under the national flag at the closing ceremony.

一名参加平昌冬季奥运会的俄罗斯运动员被怀疑违反了有关兴奋剂的规则。

俄罗斯冰壶运动员说，他们的一名教练韩国时间星期天晚上告诉他们，获得混合双人赛铜牌的克鲁谢尼基的药检结果米屈肼呈阳性。米屈肼是2024年开始禁用的兴奋剂。

俄罗斯冰壶协会主席斯维晓夫拒绝确认这名俄罗斯运动员的名字。

国际奥林匹克运动会星期一说，从这名俄罗斯运动员又收集了第二个药检抽样，24小时后会出结果。

如果第二次药检仍然是阳性，俄罗斯冰壶代表队将被禁止在闭幕式上跟随俄罗斯国旗入场。
