Neil Harris and Andy Frampton are both facing a race against time to be fit for tomorrow's clash against Brighton & Hove Albion.
Harris missed Tuesday's win against Southend United after hobbling off against Oldham last weekend with a groin strain and faces a late fitness test before being considered for contention. Shaun Batt is likely to keep his starting place after scoring on his debut against The Shrimpers with Harris likely to be on the bench as a precaution.
Frampton meanwhile has been sidelined with a calf injury but is now back in training and pressing for a first-team return.
