A Russian curler tested positive for doping Monday, after winning a bronze medal last week during the Pyeongchang Winter Olympics.
Though to the uninitiated, the idea of a curler using performance-enhancing drugs may seem freakish, the sport does demand a high level of athleticism at the Olympic level.
Meldonium was added to the prohibited list "because of evidence of its use by athletes with the intention of enhancing performance", according to WADA's website.
An worldwide sporting court on Monday formally identified a Russian curler participating at the 2018 Winter Olympics as the subject of a new doping case.
The incident is particularly embarrassing for Russian Federation given that its Olympic Association is attempting to rebuild its reputation following the International Olympic Committee-enforced ban on their participation in Pyeongchang due to systemic doping offences.
More than 160 Russian athletes who could prove they were clean from doping are competing in a Olympic Athletes from Russia (OAR) team after the nation was banned from the Games because of state-sponsored doping leading up to and including the 2014 Sochi Winter Games.
It had previously been suspected that Krushelnitsky was the Russian athlete under review.
The Court of Arbitration for Sport said Ziga Jeglic, will leave the Olympic Village after accepting the anti-doping rule violation. "The sample tested positive for meldonium, confirming the presence of the banned substance in his body", Vybornov said, reports Tass news agency.

"We express our honest regret over the fact of the incident", the delegation says in a February 20 statement.
If meldonium sounds familiar, that's because it's the same drug that got Russian tennis star Maria Sharapova suspended from the International Tennis Federation.
"As we know there is now an active case, but what I can say is what I said yesterday it is always extremely disappointing when these things happen it does show I think our systems are working here", he said.
Mark Adams spoke after curler Alexander Krushelnitsky's failed drugs test.
Three athletes have been caught doping at the Winter Olympics.
Russian women's curling coach Sergei Belanov said he didn't believe that a young and "clever man" would dope.
"I have known these guys for many years", Svishchev said. The IOC is considering lifting Russia's ban at the end of the Games and allowing the 168 athletes - minus Krushelnitsky - to march under the Russian flag at the closing ceremony this weekend.
