Russian Olympian, Darya Pishchalnikova may lose the silver medal she won in the discus at the 2012 Games in London after testing positive in a doping test, reports the Associated Press:

Russia's All Sports agency says Pishchalnikova tested positive for the banned substance Oxandrolone in a reanalysis of a sample taken in an out-of-competition control last May. The original test was negative, but her sample was checked again months later based on a more advanced testing method introduced by the World Anti-Doping Agency.
