UEFA has banned West Ham fans from attending the upcoming Europa League group game against Rapid Vienna.
A section of West Ham's travelling support were involved in crowd disturbances during the Hammers' last Europa League match, against Genk in Belgium on November 4.
The match finished 2-2, though West Ham were subsequently charged under Article 16(2)(h) of the UEFA Disciplinary Regulations relating to crowd disturbances and Article 16(2)(b) due to objects being thrown by the away fans.
As a result, the UEFA Control, Ethics and Disciplinary Body has announced the Hammers cannot take any supporters to Austria when they face Rapid Vienna on November 25. The club was also fined €34,500 in total.
David Moyes' team top Group H with 10 points from their opening four games, meaning a point in Vienna would be enough to secure progress to the knockout stage.
West Ham face second-placed Dinamo Zagreb in their final Group H match on December 9.
