The Cumbrians could include new teenage loan signing Adam Campbell in their squad for the home game this weekend.
The 18-year-old striker/winger joined the club for an initial month on Thursday and should make his debut.
Boss Greg Abbott could also be boosted by the return of central defender Sean O'Hanlon, who has yet to appear for the Cumbrians this season due to a knee injury and left-back Paul Black, on loan from Mansfield, could make his first start for the club.
But striker Lee Miller sits out the final game of his three-match ban and left-back/winger Matty Robson is still struggling with a back problem.
The Sky Blues will assess goalkeeper Joe Murphy and midfielder Adam Barton ahead of their trip to the North West.
Murphy sustained a foot/ankle injury in the Capital One Cup defeat at Leyton Orient and did not train before playing in last Sunday's thrilling 5-4 victory over Bristol City.
He has again struggled to train this week and will be checked over as late as possible before the game.
Barton, meanwhile, withdrew from training with a slight knee problem on Thursday but it is hoped he will be okay for the weekend as captain Carl Baker serves the second game of his three-match suspension.
