Due to a major doping scandal, Russia was barred from fielding an official team at the 2018 Winter Olympics. But competing under the Olympic flag as the Olympic Athletes from Russia seemed to be more of a slap on the wrist than an actual deterrent, because an OAR athlete has tested positive for a banned substance for the second time at this year's Games. And in perhaps the ultimate act of self-sabotage seen in PyeongChang to date, the athlete recently wore a shirt that said: "I don't do doping."
Bobsledder Nadezhda Sergeeva tested positive for trimetazdine, a medication typically used by sufferers of Angina, a condition of limited blood flow to the heart that results in chest pain and other symptoms. The World Anti-Doping Agency lists it as a banned substance due to its effect on metabolism. In a statement to reporters, Russian Bobsled Federation President Alexander Zubkov claimed Sergeeva "took no such medication and the team confirms she was not issued any medication."
Sergeeva's anti-doping shirt displayed a similar message, albeit one that would not age well. Per the report, she wore it a month before the Games after passing the International Olympic Committee's vetting process.
