UEFA's Control, Ethics and Disciplinary Body found the club's supporters guilty of racism during the second leg of their Champions League play-off against Ajax on Aug. 24, the governing body said in a statement on its website (www.uefa.org) on Friday.
A total of 1,500 seats in the East Stand at the Olimp 2 Stadium will be closed during the match on Sept. 28 as part of the sanction.
Rostov defender Fedor Kudryashov will be banned for three matches after being sent-off against Ajax for violent conduct, UEFA added.
Rostov are playing in the Champions League for the first time and are in Group D along with Bayern Munich, Atletico Madrid and PSV.
