Paul Hart will check on the fitness of Claude Davis ahead of his first game in charge of Crystal Palace against Sheffield United.
Davis suffered a knock just five minutes into last weekend's draw at Doncaster and had to be substituted.
Left-back Lee Hills replaced Davis with Clint Hill reverting to centre-half, but Austrian international Johnny Ertl provides another option for Hart.
Irish centre-half Paddy McCarthy remains on the casualty list, although he is stepping up his training following a long lay-off after shoulder surgery.
Midfielder Neil Danns could return after resting his back injury against Doncaster.
Teenage winger Kieran Djilali will hope to keep his place in the starting line-up after scoring his first Eagles goal last week.
Sheffield United could be boosted by the return of on-loan defender Marcel Seip to the squad.
Seip, on loan from Plymouth, was unable to play against his parent club for the Blades in last week's 4-3 home win, but will give manager Kevin Blackwell a further option in defence.
Otherwise, Blackwell is hoping to name an unchanged starting line-up after enjoying the rare luxury this season of being able to field arguably his strongest side in last week's success over Plymouth.
The Blades boss is hoping defender Toni Kallio returns from midweek international duty with Finland unscathed, but striker Darius Henderson sits out the second of a three-game ban.
Long-term absentees Gary Naysmith and Ryan France (both knee) and Derek Geary (ankle) remain sidelined.
