Police have warned supporters attending Saturday's match between Bristol City and Cardiff City they are determined to crackdown on any potential trouble.
Avon and Somerset Police carried out dawn raids on Wednesday, making seven arrests linked to disorder at the October match between the two sides in Cardiff.
The constabularies have been working with South Wales Police after events at that game left a steward requiring hospital treatment.
Inspector Rob Millican, Silver commander for the operation concerning the weekend fixture at Ashton Gate, said: "Today's operation sends out a powerful message to a small minority intent on causing problems at football games that we will not tolerate disorder.
"We are supporting colleagues in South Wales Police who are showing the red card to the small minority who caused problems at the Cardiff game in October.
"We have arrested a number of Bristol City fans and will now put these people before the courts. Successful convictions should result in football banning orders which will mean they will no longer be able to attend games or follow their national side abroad."
There are no restrictions on travel for the Cardiff fans attending the game but Police have reminded spectators that anyone carrying, lighting or throwing pyrotechnics - including flares or smoke bombs - will be arrested and could be subject to prosecution.
