Kapachinskaya and her teammates finished second, behind the US. With them being stripped of the medal that means, Jamaica and Belarus move up to the silver and bronze positions. The athlete also competed in the 400-metres in 2008, where she placed fifth, that result has also be removed from the official records. Russia have already been stripped of the 4x100m women's relay gold from Beijing.
