MOSCOW (AP) The IAAF says Russian race walker Stanislav Emelyanov has been cleared of doping after a second sample failed to indicate the presence of a banned substance.
Emelyanov, who could be a medal contender at this year's Olympics if Russia's ban from track and field is lifted, had been facing a lengthy ban for a second career doping offense. But the backup ''B'' sample did not confirm the original positive finding for EPO.
The IAAF tells The Associated Press that it ''has reserved the right to pursue Stanislav Emelyanov for other anti-doping rule violations under IAAF rules'' and is seeking legal advice, without specifying the possible violations.
Emelyanov was previously banned in 2014 for doping and was stripped of his gold medal from the 2010 European championships. He is listed as part of Russia's national team for 2016 on the Russian athletics federation website.
