Coventry City are urging City supporters planning on going to Saturday's game with Millwall at the Ricoh Arena to buy tickets before the day of the game.
Millwall have been restricted to just 1,860 tickets which have all been sold and in a bid to stop visiting supporters from going into areas for home supporters, City have said that Blocks 14-18 will only be available for pre-sale only and anyone with any previous booking history with the club this season will have their online booking cancelled without any prior notice.
