In the 2014 Olympics held at Sochi in Russia, Latvia's Oskars Melbārdis took silver behind Zubkov in the four-man bobsled event, and so he and his team should receive the gold medal, though this has yet to be confirmed by the governing body of the sport.
Zubkov is now president of the Russian Bobsleigh and Skeleton Federation but said Friday he had no intention of stepping down and would take his case to the International Court of Arbitration in Sport.
It follows a similar situation earlier in the week when Russia's Aleksandr Tretyakov was stripped of gold, meaning Martins Dukurs should get gold and his brother Tomass Dukurs should get bronze instead of the fourth-place finish he recorded at the event.
