Leeds will be without suspended teenage defender Aidy White for their home clash with Palace.
The 19-year-old was shown a straight red card for a professional foul during the recent 2-1 defeat at Ipswich and serves a one-game ban.
But manager Simon Grayson could be boosted by the return to fitness of several players as strikers Luciano Becchio (hamstring) and Billy Paynter (shin), midfielder Michael Brown (calf) and defenders Alex Bruce and Leigh Bromby were back in full training this week.
Becchio and Bruce have yet to appear this season while Paynter, Brown and Bromby have been sidelined for several weeks.
Winger Ramon Nunez is hoping to benefit from Max Gradel's departure to St Etienne by returning to the starting line-up with Ross McCormack seeking to resume his partnership alongside Andy Keogh up front. New signing Mikael Forssell is also available.
Anthony Gardner and Antonio Pedroza could be added to Crystal Palace's squad for game.
Centre-half Gardner re-signed for the Eagles three weeks ago following his successful loan spell last season but was not considered until he had built up his fitness.
Palace this week received international clearance for young striker Pedroza, who was signed before the transfer deadline from Mexican club Jaguares.
Boss Dougie Freedman is still without full-back Nathaniel Clyne (foot), midfielders Kagisho Dikgacoi (hamstring) and Alex Marrow (ankle) and striker Steffen Iversen (hamstring).
Defenders Peter Ramage and Aleksandar Tunchev have extended their loan deals but Ryan McGivern and Alassane N'Diaye have left Selhurst Park since the 1-1 draw with Blackpool last time out.
