Chesterfield fans travelling to Derby for tomorrow’s FA Cup game are being reminded that the fixture is a sell-out.
The Spireites have sold their 5,700-seat allocation for the game, which kicks off at the iPro Stadium at 3pm.
No tickets for away supporters will be available on the day and fans are being urged not to head to the ground if they do not already have a seat.
There will be extra police in Derby, on key routes to the stadium and at the train station.
Superintendent Graham McLaughlin, of Derbyshire Police, said: “This fixture will be extremely popular with both home and away fans and we want them to be able to enjoy the game safely.
“Anyone who causes trouble or is excessively intoxicated will be removed from the ground or barred entry.”
