Lewis Grabban could be out until mid-March with the injury he suffered in Sunday’s 2-1 defeat at Cardiff City.
The Reds’ leading scorer was clattered by Will Vaulks at the Cardiff City Stadium and had to be helped off the pitch.
Losing the experienced marksman for any length of time would be a blow for the Reds in their quest to land a play-off place, although Steve Cooper added two strikers to his squad, with Keinan Davis and Sam Surridge arriving during the transfer window.
