Police officers from across the country have been drafted in to help Suffolk Police control football fans in Ipswich tomorrow.
350 officers and dozens of dogs and horses will patrol the streets from Ipswich railway station to Portman Road for the first local derby since 2011.
The game was originally scheduled for Sunday but changed at the request of both sets of supporters.
The last time the two teams met in April 2011 Norwich City won 5-1.
The match kicks off at 12.15pm at Portman Road, Ipswich.
