Saturday's 3-0 win over Yeovil came at a cost with goalkeeper Rob Green suffering suspected cracked ribs and midfielders Armand Traore and Jermaine Jenas picking up hamstring injuries.
All three are set to miss out at Hillsborough while two-goal Ravel Morrison needs a fitness check after feeling a groin problem late on.
Benoit Assou-Ekotto could miss out again with the knock he suffered at Brighton last Tuesday while fellow full-back Danny Simpson (back), midfielder Ale Faurlin (knee), winger Matty Phillips (ankle) and strikers Charlie Austin (shoulder) and Andrew Johnson (ankle) remain on the sidelines.
