Centre-back Jerel Ifil will continue in defence after making his debut during Saturday's 1-0 defeat at Brentford but fellow defender Dave McCracken will again miss out with a hamstring problem.
Byron Anthony will also miss out as he continues to struggle with an ankle injury picked up in training last week.
Midfielders Ben Swallow (ankle) and Wayne Brown also picked up knocks in training and will miss the game, although the pair are not expected to be sidelined for too long.
Youngster Charlie Clough has joined Blue Square Bet Premier side Bath on a month's loan and midfielder Stuart Campbell will not be risked despite returning to training following a hamstring problem.
