Bristol City fans travelling to Swansea for a match have been banned from driving there or arriving by train.
City fans will not be allowed into the match unless they arrive by coach
South Wales Police have taken the unusual step of warning supporters they must come into the city on official coaches, or face being turned away.
City play the Welsh side at the New Stadium on Saturday, but police fear a repeat of the violence that marred the team's trip there in 2000.
A police dog was partially blinded in a fight that broke out on that occasion.
Major, a five-year-old German Shepherd, was hit by a bottle thrown during the brawl and lost his right eye, forcing him to retire from service.
Only supporters who buy a ticket for one of the official coaches will be allowed to purchase tickets for the match itself.
A spokesman for South Wales Police confirmed fans arriving by train will also be turned away and said he believed it was the first time the force had taken such action.
Superintendent Julian Williams said: "We are working with the stadium management company to ensure the match is enjoyed by all in attendance and the initiative in relation to travelling fans is to ensure the safety of people in and around the venue.
"It is disappointing that there are certain individuals intent on causing problems either within the stadium or outside, when visiting fans arrive and leave the venue.
"We will not tolerate this, and persons who behave in a disorderly manner can be assured they will be arrested and banned by the courts from future football matches."
