Coventry's Clive Platt and Ben Turner are major injury doubts for the trip to Nottingham Forest.
Striker Platt limped off after half an hour of Saturday's 3-2 loss to Leeds after picking up a thigh strain and could miss out possibly paving the way for former Forest player Marlon King to make only his second start for the Sky Blues.
Centre-back Turner, who scored at the weekend, is almost certainly out after he left the Ricoh Arena on crutches with his left knee in a brace suffering from suspected medial ligament damage.
Freddy Eastwood (knee) and Chris Hussey (broken metatarsal) are expected to be in contention for a place in the squad for the first time since August after both returned to full training.
Midfielder David Bell (groin) also returned to training on Friday but the match may come too soon for him while centre-back James McPake is also on the verge of making his comeback.
Aidy Boothroyd's side currently sit fifth in the npower Championship and are on a four-match unbeaten run on their travels.
