RIO DE JANEIRO (AP) " For the third time in a week, Russia was stripped of a track-and-field medal Saturday after another athlete tested positive in a reanalysis of doping samples from previous Olympics.
Evgenia Kolodko was disqualified and stripped of the silver medal in the women's shot put from the 2012 London Games after her stored samples came back positive for two banned substances, the International Olympic Committee said.
The IOC asked the IAAF to modify the results and consider further sanctions against the 36-year-old Kolodko, who could face a two-year ban.
Kolodko was one of 98 athletes caught in the retesting of more than 1,000 samples from the London Olympics and 2008 Beijing Games.
The IOC stores samples for 10 years to allow them to be reanalyzed when improved methods become available.
The IOC said Kolodko tested positive for the steroid turinabol and ipamorelin, which is classified as a peptide hormone on the World Anti-Doping Agency's list of banned substances.
Kolodko's disqualification marks the latest shake-up in the medals in the women's shot put in London.
The Russian had been bumped up from bronze to silver after Nadzeya Ostapchuk of Belarus was stripped of the gold medal the day after the London Games because of a failed drug test. New Zealand's Valerie Adams was promoted to the gold, with Gong Lijiao of China moved up from fourth to bronze.
Now, Gong could move up to silver and Li Ling of China from fourth to third.
Earlier this week, Russia was stripped of two women's relay medals from the Beijing Games. Russia lost the silver in the 4x400 after Anastasia Kapachinskaya tested positive, and gold in the 4x100 after Yulia Chermoshanskaya failed a test.
Saturday's decision was another black eye for Russia, whose track-and-field team was banned from the Rio de Janeiro Olympics over allegations of state-sponsored doping. Investigations are continuing into wider systematic doping in Russia involving dozens of other summer and winter Olympic sports.
