The Court of Arbitration for Sport (CAS) on September 3 banned Russian athlete Tatyana Tomashova, a two-time world champion, for 10 years. The lengthy ban was imposed because it was her second offense after she was handed a two-year ban in a case that prevented her from competing in the 2008 Beijing Olympics. The Russian athlete also was sanctioned with "disqualification of all competitive results" from June 2012, to January 2015 -- a period that included the 2012 Olympics in London. The court said Tomashova tested positive for anabolic steroids in a re-analysis of samples she gave prior to the London Games. The decision means the bronze medal in the 1,500-meter race will go to U.S. runner Shannon Rowbury.
