Jonathan Parr could be missing from the Crystal Palace side when play-off rivals Leicester visit Selhurst Park.
Full-back Parr suffered an ankle injury during Tuesday night's 3-0 defeat at Ipswich and hobbled off after half an hour to be replaced by Jazz Richards.
The Eagles will still be without skipper Mile Jedinak, who serves the second game of a two-match ban for collecting 10 yellow cards this season, but fellow midfielder Owen Garvan is close to returning after a knee injury.
Defender Paddy McCarthy misses out against his old club with a long-term groin problem and midfielder Alex Nimely is sidelined by a hamstring injury.
Winger Jason Banton could be in the squad after he was recalled from a loan spell at Plymouth.
Leicester will have an unchanged squad for the crucial clash against fellow play-off contenders.
The Foxes reported no new problems following Tuesday night's enthralling 3-2 home win over Bolton, so manager Nigel Pearson once again has everyone fit and available.
Pearson made two changes against the Trotters, recalling wingers Anthony Knockaert and Lloyd Dyer at the expense of central midfielder Danny Drinkwater and leading scorer David Nugent.
Bringing natural width back into the team worked as the Foxes won for the first time in 10 matches and replaced their opponents in the play-off places.
Midfielders Richie Wellens and Paul Gallagher, defenders Liam Moore and Zak Whitbread and strikers Jamie Vardy and Harry Kane join Drinkwater and Nugent in providing options for Pearson should he wish to change his starting line-up.
Successive league victories for the first time since mid-January would see Leicester leapfrog Palace into fifth place in the table. The Foxes could even be fourth come Saturday evening if they win and Brighton fail to beat Blackpool.
