CSKA Moscow midfielder Roman Eremenko has been given a two-year ban for testing positive for cocaine after a Champions League match against Bayer Leverkusen in September.
The 29-year-old's ban starts on Oct. 6, which is when the Finnish international was provisionally suspended.
Eremenko, who was born in Moscow but raised in Finland, played for CSKA in their 1-0 home defeat by Tottenham a fortnight after his positive test but a week before UEFA started disciplinary proceedings.
A statement from the European governing body's control, ethics and disciplinary board said "the presence of cocaine" was found in his sample and the drug is classified as a stimulant by the World Anti-Doping Agency when used in-competition.
"This decision may be appealed against within three days of receipt of the written reasoning," the statement added.
Eremenko has played 73 times for Finland as well as enjoying successful stints with Dynamo Kiev and Rubin Kazan. He was the Russian Premier League's player of the season in 2014-15.
