Nigel Pearson has ruled Matty James and Kal Naismith out of the game with Preston on Wednesday and admits they remain doubts for the weekend visit of Millwall.
Naismith is currently sidelined with a calf injury picked up in the 0-0 draw with Coventry that forced him off the field five minutes before half-time. Last Thursday, Pearson admitted the injury is better than initially feared although he would be out of action for around 10 days.
James will also miss his fourth consecutive game having undergone a minor operation on his groin. The 31-year-old was last seen before the international break after playing 76 minutes in the 2-1 defeat at Burnley.
