In January, the Russian Anti-Doping Agency (RUSADA) opened four cases of possible violations of anti-doping rules by athletes, reports TASS.
In just 12 months last year, 108 possible violations were identified. According to the World Anti-Doping Code, the names of violators can only be released after an investigation is completed.
Earlier it became known that RUSADA employees from 2019 to 2020 checked the 2015 world hurdles champion Sergei Shubenkov for doping five times. It was last checked at the end of August last year at the Russian Cup in Bryansk.
