Skipper Sammy Clingan and striker Cody McDonald will both be hoping for involvement in Coventry's crucial home clash against Barnsley.
The pair have returned to training this week following spells on the sidelines nursing groin and knee injuries respectively but it remains to be seen how much manager Andy Thorn will gamble on their fitness.
Neither have got any game time under their belts and are likely to have to watch from the bench as the Sky Blues aim to build on an impressive recent home record which has seen them win four of their last five at the Ricoh Arena.
Midfielders David Bell (virus) and Conor Thomas (adductor) returned among the substitutes for last weekend's disappointing 2-0 defeat at Nottingham Forest, while Nathan Cameron (knee) is also back in training.
That just leaves fellow defenders Richard Wood (knee) and Hermann Hreidarsson (shoulder) on the sidelines.
Barnsley defender Stephen Foster is, however, hoping to shake off illness in time for the clash.
Foster is one of several players to have been hit by a virus this week, but manager Keith Hill has no new injury or suspension problems.
Teenage midfielder Paul Digby made his full debut in the midweek home defeat to Birmingham and Hill must decide whether to keep the 17-year-old in his starting line-up or recall Michael Tonge, on loan from Stoke.
Stephen Dawson (ankle) must wait at least another week before coming into contention for his first appearance for the Tykes following his arrival from Leyton Orient in January.
Another midfielder, David Perkins, remains sidelined with a hamstring problem and defender Bobby Hassell is still nursing a knee injury.
Winger Jim O'Brien is pushing for a recall after being rested in midweek following his return from a long-term groin injury and defender Scott Golbourne is also in contention to start.
