Tony Mowbray is hoping that Jim O'Brien will be ok for the trip to Chesterfield on Saturday.
O'Brien was forced off during the 1-1 draw with Bradford City with what Mowbray described on Tuesday night as "feeling his hamstring a bit".
The captain did not train today but Mowbray has said that he will be assessed tomorrow ahead of the game.
Mowbray could be without Aaron Phillips who went off on Tuesday with concussion but has said that City need to get Reda Johnson and James Maddison fit as quickly as possible.
