This is reported on the CAS website.

The International Bobsleigh and Skeleton Federation (IBSF) in January 2019 disqualified Zubkov, Kasyanov, Pushkarev and Khuzin until December 2020 for violating anti-doping rules at the 2014 Games in Sochi.

The Russians, in turn, have filed appeals with the CAS.

Nevertheless, CAS fully accepted the IBSF decision.

Zubkov won two gold medals of the Games in Sochi in the competition of twos and fours.

Subsequently, he was found guilty of violating anti-doping rules at the Games in Sochi and was deprived of the awards won at the home Olympics, and was also suspended from participation in the Games for life.

Later, the Court of Arbitration for Sport softened the IOC's verdict, reducing the suspension from life to missing the 2018 Games.

Earlier, the head of the SBR commented on the deprivation of gold medals for Yevgeny Ustyugov due to doping.
