Several so called Bristol Rovers supporters were arrested at Derby on Saturday as Police had to deal with trouble both before and during the Cup game.
Police bussed 160 Bristol Rovers fans, described as "risk supporters", from the city centre and took them to the game to avoid further disorder.
"If they had been allowed to walk through the town, we could have had major problems," said a Police spokesman.
Twelve arrests were made, and Police said investigations were continuing and more arrests and charges were likely to be made.
The Derby press reported that there had been treats of trouble made on internet chatrooms.
Rovers were said to have taken close to 6,000 to the game.
Last May Hereford United took over 10,000 to Leicester for the Conference Play-off final.
