Uefa has opened disciplinary proceedings against Dynamo Kiev in response to crowd disturbances and racist behaviour during their Champions League match against Chelsea on Tuesday.
Jose Mourinho's Chelsea side hit the post and bar in a 0-0 draw in the Ukrainian capital.
The point leaves the Blues third in Group G, a point behind Dynamo.
European football's governing body will deal with the case on 27 October.
Uefa received reports from anti-discrimination group Fare that four men were attacked by other Dynamo fans in a home section of the Olympic Stadium.
Last season, Dynamo were fined and ordered to close part of their stadium on two occasions as punishment for racist behaviour in the crowd at Europa League matches.
