CSKA Moscow midfielder Roman Emerenko has been handed a two-year ban from football after he tested positive for cocaine.
The Daily Mirror reports that the Finish international's A sample found traces of the drug after he was tested following the club's recent Champions League encounter with Bayer Leverkusen in September.
He has the right to contest the result of the test, but as yet it's not known what course of action he will take.
The player has three days to make a response, and the news will come as a shock considering he was the Russian league's Player of the Season for 2014/15.
He was also capped 73 times for Finland, scoring five times, but should the ban stand he won't be eligible to return until he's 31.
An official statement released by UEFA read: "The UEFA Control, Ethics and Disciplinary Body (CEDB) has notified today its decision in relation to PFC CSKA Moskva player, Roman Eremenko.
"The Finnish player has been suspended for 2 years from all competitions, following the positive result of a doping control test in competition undergone by the player after the UEFA Champions League group stage match between Bayer 04 Leverkusen and PFC CSKA Moskva played on 14 September 2016 in Germany.
"The analysis of the A sample revealed the presence of cocaine and its metabolites, a stimulant that is classified under the category of prohibited substances in the World Anti-Doping Agency (WADA) 2016 Prohibited List under class S6, being prohibited in-competition.
"The player was found guilty of being in breach of the UEFA Anti-Doping Regulations, Edition 2016. As a result, the UEFA Control, Ethics and Disciplinary Body decided to impose a two-year ban on Roman Eremenko, starting from 6 October 2016 date of the provisional suspension.
"This decision may be appealed against within three days of receipt of the written reasoning."
Emerenko began his career in Finland with Jaro before heading for a spell in Italy with Udinese and Sienna.
However, the bulk of his career has been spent in eastern Europe and he can count stints with the likes of Dynamo Kiev and Rubin Kazan before he made the move to Moscow in 2014.
He was a part of CSKA's title winning team last season and has made a total of 76 appearances for the club, scoring 20 times.
