A second Russian athlete has tested positive for a performance-enhancing drug at the Pyeongchang Winter Olympics, a major blow for the nation's hopes of regaining its Olympic status and drawing a line under years of doping scandals.
Bobsledder Nadezhda Sergeeva tested positive for a heart drug on Feb. 18, five days after a previous doping test returned a negative result for her, the Russian bobsleigh federation said in a statement on Friday.
"On Feb. 13, her sample was clean. The team's medical staff did not prescribe the drug to the athlete," the federation said in a post on its official Facebook page.
"The Bobsleigh Federation of Russia and the athlete herself understand the extent of their responsibility and understand how what has happened can have an impact on the fate of the whole team."
Earlier this week, Russian curling medallist Alexander Krushelnitsky agreed to hand back his mixed-team bronze medal after testing positive for meldonium, which can aid in endurance.
Krushelnitsky's case shocked the Russian athletes, who are competing at the Games as neutral athletes as punishment over allegations that the sporting powerhouse ran a systematic, state-backed doping programme.
