The International Olympic Committee (IOC) did not include Russian athletes in the list of invited to the 2018 Olympic Games, because they appear in the base of the Moscow Anti-Doping Laboratory.
This is with reference to their sources, "Soviet Sport".
"The main role was played by the electronic database of the Moscow Anti-Doping Laboratory, which was available to WADA in November 2017. It contains all the results of testing Russian athletes in the period from January 2012 to July 2015. Based on this information, the applications of Russian athletes for participation in Pyeongchang-2018 are rejected, "the message says..
In total, we are talking about 111 athletes. Among them are the six-time Olympic short track champion Victor An, the Olympic champion Sochi-2014 biathlete Anton Shipulin, two-time world champion skier Sergei Ustyugov. These athletes, as stated by the vice-president of the Russian Olympic Committee Stanislav Pozdnyakov, were not involved in the proceedings in the framework of Denis Oswald's commission and were never involved in doping stories.
Recall, on December 5, the IOC suspended the membership of the Russian Olympic Committee, and the Russian national team was suspended from the 2018 Olympics. "Pure" Russian athletes can perform in Pyeongchang under the Olympic flag.
The decision was made on the basis of the conclusions reached by the two commissions: Denis Oswald and Samuel Schmidt. The first was engaged in a re-examination of doping samples of participants of the Olympic Games in Sochi, the second investigated the involvement of Russian officials in doping frauds.
