Goalkeeper Federici is still sidelined by an ankle problem, meaning third-choice Stuart Taylor will again deputise following last weekend's 2-1 defeat to Aston Villa.
That defeat prompted Brian McDermott's dismissal as manager, with the club four points from safety, and caretaker boss Eamonn Dolan will also be without winger Kebe (groin). Pavel Pogrebnyak serves the last part of his three-game ban while fellow striker Jason Roberts (hip) is likely to miss the rest of the season.
