Russian midfielder Yegor Titov has been banned by Uefa for 12 months after failing a routine drugs test.
Titov was once targeted by Bayern Munich
The 27-year-old was found to have the stimulant Bromantan in his system after Russia's Euro 2004 play-off against Wales on 15 November last year.
He will now miss the Euro finals in June and Uefa has asked world governing body Fifa to extend the ban worldwide.
Titov has until 26 January to appeal, with the ban due to run until 21 January next year.
He has also been fined £4,420, while Spartak have received a £8,840 fine.
Titov, who plays for Spartak Moscow, was once hailed as one of the most promising playmakers in the game but his career has been dogged by injuries.
Despite his injury, Titov won the Russian Player of the Year award twice.
