The Spireites may have not played during the last week but they remain strongly placed in the League One play-off chase.
Bradford edged ahead of Chesterfield, pushing them down to tenth, with a 1-1 draw at Coventry City on Tuesday night.
And it ensured the Spireites remain two points off sixth spot, the gap with which they finished their blank weekend.
Coventry visit the Proact on Saturday with Chesterfield looking to twist the knife on the Sky Blues, who have failed to win since Tony Mowbray took charge last week.
The Sky Blues sit just two points clear of the bottom four, though 21st placed Leyton Orient have a game in hand.
City lost full-back Aaron Phillips to injury early in the second half on Tuesday and he is doubtful for Saturday’s trip to the Proact.
Paul Cook will only be without the services of suspended Sam Morsy after Dan Jones ankle was passed fit by physio Rodger Wylde.
Morsy’s absence gives former Coventry player Cook a selection headache as there is no obvious direct replacement.
Jones, Ritchie Humphreys and Ashley Carson are the three men battling for the vacancy with Humphreys favourite for the slot as his involvement would negate the need for switching any more of the team around from the side that won 2-1 at MK Dons last time out.
Caolan Lavery, whose loan from Owls has been extended this week, will be looking for a third goal in three games having scored the last minute winner at MK Dons last midweek and also in the comfortable 3-0 win over Fleetwood Town in the Spireites’ last home game.
