Luton Town fans will not be able to use pubs in Watford when the two rival football clubs face each other on Sunday.
Hertfordshire Police said it was licensees that had taken the decision to not serve Hatters fans when their team takes on the The Hornets in the Championship battle at Vicarage Road.
The force warned home fans they would not be allowed to exit the stadium via Vicarage Road itself until away fans had left after the match which kicks off at 12:00 GMT.
Ch Insp Ian Grout said: "Our primary role is safety… Watford fans will be free to leave through Cardiff Road or into Harwoods Road into west Watford.
