Hundreds of police officers will be on duty tomorrow for the Rotherham v Leeds derby.
Police chiefs said there would be high visibility policing in both Rotherham town centre and Sheffield city centre.
Officers will also be working on the railway as fans travel to and from the 7.45pm match at New York Stadium.
Chief Inspector Richard Butterworth said: “I want to reassure the public in Rotherham and Sheffield that we will not tolerate any level of disorder or violence.
“We have jointly planned a large and robust operation for this match with West Yorkshire Police and British Transport Police and we will be able to provide a prompt and effective police response to
any issues or concerns. We will not accept or stand for anyone intent on causing trouble or inciting violence.
“The match is completely sold out and there are very few pubs actually showing the event in Rotherham or Sheffield.
“I would strongly advise people without tickets to not travel into the town and consider making other arrangements to watch the game.
“I will ensure that we provide a safe and welcoming environment for fans who just want to attend and enjoy the game and endeavour that there is as little disruption as possible for people conducting their daily business in the town.”
