LAUSANNE: Yarelys Barrios of Cuba has been stripped of the silver medal in the women's discus from the 2008 Beijing Olympics after testing positive in a reanalysis of her doping samples.
The IOC says Barrios tested positive for acetazolamide, a banned diuretic and masking agent.
She has been retroactively disqualified and loses the silver medal, which now stands to go to Olena Antonova of Ukraine. China's Song Aimin is in line to move from fourth to bronze.
Barrios also competed at the 2012 London Olympics, where she was upgraded to the bronze medal after a Russian was stripped of the silver for doping.
Also Thursday, Qatari sprinter Samuel Adelebari Francis was disqualified from the Beijing Games after testing positive for stanozolol. He was eliminated in the 100-meter heats and did not start in the 200.
