Ticket sales suspended for Chesterfield's trip to Coventry
The move was made due to uncertainty over whether the fixture will go ahead following international call-ups affecting the Spireites.
Liam Graham has been named in the New Zealand squad and Ryan Fulton has been called-up to the Scotland U21 squad ,while Connor Dimaio is on standby for the Republic of Ireland U21s.
If Dimaio is named in the squad, Chesterfield could make a request for the Coventry match to be postponed.
