SALZBURG, Austria (AP) " Ukrainian biathlete Sergei Sednev, a bronze medalist at the 2011 world championships, faces a possible two-year ban after a retest of a stored doping sample came back positive for EPO.
The International Biathlon Union said Monday that Sednev was targeted as part of a program to re-test older samples which "showed atypical results in the previous seasons."
Sednev's re-analyzed sample was collected in an out-of-competition test in Antholz, Italy, in January 2013. The IBU said the sample was retested at a World Anti-Doping Agency lab and was positive for the banned blood-booster EPO.
The Ukrainian biathlon federation said in a statement Monday it had questioned Sednev, who "could not explain or disprove" the test results.
Sednev, who won a bronze medal in the relay at the 2011 championships, announced last month that he was retiring at the age of 31.
