Leicester will have Jeffrey Bruma available again for the visit of Palace.
However, the on-loan Chelsea centre-half may struggle to get back into the team after City kept a clean sheet in an impressive 4-0 victory over Burnley on Saturday while he served a one-match ban.
Fellow defender Kyle Naughton also missed that game through illness and he could also return to the squad.
Manager Sven-Goran Eriksson is blessed with options should he wish to make changes, with full-back Bruno Berner, midfielders Lloyd Dyer and Yuki Abe and forwards Darius Vassell and Steve Howard also available for recalls.
Victory would put Eriksson's side right back in the hunt for a play-off spot, with games against top-six rivals Reading and Nottingham Forest next up for the Foxes.
Palace could be unchanged for the trip.
Boss Dougie Freedman has no new injury worries following the narrow 2-1 defeat at Ipswich on Saturday.
Alex Marrow remains on the sidelines with an ankle injury and fellow midfielder David Wright is not expected to be fit having missed the last two games with a calf injury.
Ipswich loanee Pablo Counago is available after he was ineligible to face his parent club at the weekend but he will probably be on the bench along with fellow forward Jermaine Easter, who hopes to shake off a knock.
Defender Paddy McCarthy will captain the Eagles against his former club.
Scunthorpe's surprise 4-1 win over leaders QPR on Saturday cut the gap between Palace and the relegation zone to just five points with six games remaining.
