DEMONSTRATIONS by the British National Party and Unite Against Fascism in Rotherham passed peacefully, police said.
Seven BNP supporters were given section 27 dispersal orders. Two were arrested for breaching these orders.
About 40 turned out for the far-right party near the B&Q roundabout to protest plans for a replacement Chapel Walk mosque.
Sixty extra officers were on duty in the town centre to assist with Cardiff fans stopping off in Rotherham before their match at Sheffield Wednesday.
Three travelling fans were arrested at Hillsborough for damage, throwing an object and trying to enter the ground while drunk.
South Yorkshire Police said the fixtures at Doncaster Rovers and Barnsley had passed with “minimal issues.”
Chief Supt Jason Harwin said: “I’m pleased that the demonstrations and football games passed with very little disruption and no disorder.
“Residents in Rotherham were able to go about their usual business and I would like to thank everyone for their cooperation.”
