Fenerbahce duo Mason Greenwood and Matteo Guendouzi have been suspended for their part in the chaotic scenes after their club's Champions League playoff second leg against Lyon.
Last month's 2-1 victory for Fenerbahce in France meant the Turks progressed 3-2 on aggregate, and after the final whistle, Greenwood and Guendouzi, who both previously played for Lyon's bitter rivals Marseille, were involved in a brawl with players and coaching staff from both sides.
Former Arsenal midfielder Guendouzi has been suspended "for a total of four Uefa club competition matches for which he would otherwise be eligible, for insulting others present at the match, provoking spectators and for violating the basic rules of decent conduct", Uefa announced in a decision made public on Friday evening.
Two of the matches are subject to a "one-year probationary period", European football's governing body added in the statement.
Guendouzi, who was also fined 50 000 euros ($58 000), was found guilty, among other things, of giving the middle finger to Lyon supporters and of provocations that led to a scuffle after the match.
His English teammate Mason Greenwood, formerly of Manchester United, received a one-match suspended ban and was fined 30 000 euros for "violating the basic rules of decent conduct".
