Russian heptathlete Chernova loses medals in doping case
LAUSANNE, Switzerland (AP) Russian heptathlete Tatyana Chernova has been stripped of a world championship gold medal and an Olympic bronze medal because of a doping offense.
The Court of Arbitration for Sport on Tuesday also handed Chernova a ban of 3 years, 8 months, for a separate blood doping violation.
Russian runners Ekaterina Sharmina and Kristina Ugarova also received doping suspensions based on evaluation of blood samples in their biological passport profiles.
Chernova had previously been given a two-year ban backdated to 2013 after testing positive for a banned steroid when a sample from the 2009 world championships was reanalyzed.
CAS ruled Tuesday that all of Chernova's results between Aug. 15, 2011, and July 22, 2013, are annulled.
That means she loses her gold from the 2011 world championships in Daegu, South Korea, and bronze from the 2012 London Olympics.
