Sol Bamba and Darius Vassell are the only absentees for manager Nigel Pearson for his first game back in charge of Leicester.
Bamba is suspended after collecting his fifth yellow card of the season during the home defeat to Leeds prior to the international break. The centre-half must serve a one-match ban.
Vassell missed that game after scans revealed the former England striker had suffered cruciate ligament damage in the defeat at West Ham at the end of October. He has since been ruled out for the remainder of the campaign.
Aleksandar Tunchev returned from a loan spell at Palace during the break. The Bulgarian defender has been nursing a groin injury but he trained this week and is in contention to face his most recent club.
Pearson, back at Leicester after 17 months away as manager of Hull, insists the chance to win a place in his first starting XI on Sunday is open to every member of the squad.
"People have a clean slate and the onus is very much on the players to be picked for the side. We will give everyone every opportunity because this job is about players, not managers. My job is to facilitate success on the pitch," said Pearson. "There are players that will know me and know what to expect, but those that don't will perhaps be unsure and not know what to expect. They need to be assured that they will be treated fairly."
Chris Martin is in line to make his Palace debut.
The striker this week moved to Selhurst Park on loan from Norwich until January to boost a Palace side who have not scored in their last three matches.
However, the Eagles were dealt a huge injury blow on Tuesday night when midfielder Jonathan Williams suffered a broken leg playing for Wales' Under-21s.
Since Palace's last outing a fortnight ago, defender Aleksandar Tunchev has returned to Leicester at the end of his loan spell and midfielder Andy Dorman has joined Bristol Rovers on loan.
Alex Marrow is still on the sidelines with an ankle problem and Lee Hills is recovering from a long-term knee injury.
