Shrewsbury Town are asking Coventry City supporters who do not have a ticket for Saturday's game to stay away.
The Shrews have suspended on-line booking after reports of City supporters trying to buy tickets in home areas, after the Sky Blues allocation of 1600 tickets sold out.
Shrewsbury have confirmed there will be no sales to City supporters on the day of the game.
