PYEONGCHANG, Korea, Republic Of -- Russia could lose its chance to be reinstated before the end of the Winter Olympics because of a doping charge against curling bronze medallist Alexander Krushelnitsky.
The Monday that it has "initiated a procedure involving" Krushelnitsky, who finished third in mixed doubles with his wife, Anastasia Bryzgalova.
IOC spokesman Mark Adams says a failed doping test could keep Russia's banned team from marching under the national flag at the closing ceremony.
Russian athletes are participating in the Pyeongchang Olympics as "Olympic Athletes from Russia." The IOC suspended the Russian Olympic committee last year in connection with a massive doping scheme at the 2014 Olympics in Sochi but allowed 168 athletes to compete under neutral uniforms and without the Russian national flag.
Adams confirmed the positive test and says it could have "consequences" in evaluating the behaviour the Russian team, which was required to abide by restrictions -- including bans to some medal favourites -- and to undergo extra drug tests.
"If confirmed this will be taken into account along with many other factors" regarding Russian behaviour," Adams said.
Russian Curling Federation president Dmitry Svishchev told The Associated Press that Krushelnitsky tested clean as recently as January 22, the day before he flew to a pre-Olympic training camp in Japan.
Svishchev said it was possible someone spiked Krushelnitsky's food or drink with meldonium, which was banned in 2016. He suggested that rival Russian athletes or Russia's political enemies could be responsible.
"It can't happen at the Olympic Village because everyone eats the same canteen food," he said. "It could happen at training camp or in the intervening period. ... There's a possibility of it being something within the team, that something happened during training camp, or as a political means to achieve some goal."
The curling team trained in Japan in January, bringing in some Russian athletes who had not qualified for the Olympics as practice partners.
Meldonium is the substance that Russian tennis star Maria Sharapova was suspended for after testing positive at the Australian Open in 2016. Before it was banned, many Russian athletes used the drug, which is designed for people with heart problems and some believe can help athletes increase stamina.
Krushelnitsky's "A sample" tested positive. Adams said a second sample would be tested, and results could be announced within 24 hours.
The Norwegian team finished fourth, and could get the bronze if the positive test is confirmed.
Adams says Russians at the games have undergone "rigorous testing" and adds that "Russians were tested to a significant level more than others."
The case was the talk of the rink at curling.
Russian women's curling coach Sergei Belanov said he didn't believe that a young and "clever man" would dope. "It's stupid. But Aleksandr is not stupid, so I don't believe it."
The skip of the Russian women's team, Viktoria Moiseeva wanted to comfort Krushelnitsky and Bryzgalova but "we thought that there are no words to comfort now. We just tried to stay away."
Though to the uninitiated, the idea of a curler using performance-enhancing drugs may seem bizarre, the sport does demand a high level of athleticism at the Olympic level. Curlers need to have strong core muscles and upper body strength in order to manage the often rigorous sweeping that helps them guide the rock down the ice.
Fitness is even more important in mixed doubles, the event Krushelnitsky was competing in. Because there are just two curlers on each team instead of the four in traditional curling, there is little rest between throws, and both teammates are often heavily involved in sweeping.
"It's physically demanding out there. It's not like you don't need any muscles," said Swiss curler Silvana Tirinzoni, whose team beat the Russian women's team 11-2 at Monday's round robin. "We have to be fit and we have to be working out. My sweepers are working out like five times a week, go to the gym, so it (performance-enhancing drugs) can help, but we shouldn't do that. I think that's stupid."
Tirinzoni said if the reports were confirmed, they would be disappointing. But she said she still had no reservations about playing against the Russian athletes on Monday.
"I think clean athletes have the right to compete," she said. "It's not about me to make those kind of decisions. So I believe the team we played today, they are as clean as we are."
