West Ham have accepted a Uefa sanction banning their fans from travelling to the Europa League game at Rapid Vienna.
In a statement West Ham said they "reluctantly" accepted sanctions but "also wish to place on record our disappointment at the extremely short notice of the measures."
The game against Rapid Vienna takes place on Thursday 25 November.
The Premier League club, who were also fined a total of 34,500 euros (£30,000), said that they were working to identify the fans responsible for the disturbance.
"West Ham United condemn the behaviour of this group of individuals," the statement added.
