In December 2017, Russian defenseman Inna Dyubanok became one of eight Russian women's hockey players sanctioned after the Oswald Commission investigated anti-doping violations connected to the 2014 Winter Olympics in Sochi. The commission's findings led to the disqualification of the players' results from the women's ice hockey tournament, placing Dyubanok's Olympic record under the same cloud that engulfed Russia's wider Sochi doping scandal. Dyubanok had played all five games for Russia at the 2010 Olympics, but the 2014 case concerned her participation in the home Games, where the integrity of Russian performances was being scrutinized as part of the investigation into alleged sample tampering and institutional doping practices. The available account does not identify a specific banned substance or describe Dyubanok personally as part of a doping ring; it records her sanction as an Oswald Commission anti-doping ruling.
All eight players appealed. Five succeeded in having their sanctions and the associated disqualifications annulled, but Dyubanok, Galina Skiba, and Anna Shibanova were the exceptions: the penalties against them were upheld. That distinction made the case especially consequential, because it separated the three players from teammates whose Olympic records were restored and left their own Sochi results officially disqualified. The episode became part of the continuing fallout from the Sochi scandal, in which the IOC attempted to distinguish proven individual violations from broader allegations surrounding Russian sport. It also left Dyubanok's Olympic legacy permanently tied to one of the most controversial anti-doping investigations in modern Games history.
