Eagles hope to play Jazz
Crystal Palace will check on Jazz Richards ahead of the visit of Leeds.
The on-loan Swansea defender missed Tuesday night's 4-2 win over Hull due to a toe injury, with midfielder Kagisho Dikgacoi filling in at right-back.
Brazilian attacker Andre Moritz is fit after an ankle injury and should be involved, but defenders Paddy McCarthy and Joel Ward (both groin) and midfielders Owen Garvan (knee) and Alex Nimely (hamstring) are still on the sidelines.
Boss Ian Holloway is considering resting 28-goal top scorer Glenn Murray with Stephen Dobbie, Aaron Wilbraham and Tuesday's hat-trick hero Kevin Phillips all vying to start up front.
Winger Yannick Bolasie could also return to the starting line-up after dropping to the bench against the Tigers.
Leeds manager Neil Warnock is hoping to name an unchanged side for the fifth successive game.
Warnock has no new injury or suspension problems following the midweek draw at Leicester as Leeds bid to keep their faint play-off hopes alive.
"The way we're playing at the moment I'd like to go unchanged for the rest of the season," Warnock told the club's official website.
"There's nothing new injury-wise after the other night.
"We did have a few knocks and what have you before the game at Leicester, but the players came through it ok."
Lee Peltier will continue to skipper the team alongside Tom Lees in central defence, with Stephen Warnock in the left-back role and Sam Byram at right-back.
Michael Tonge, Paul Green, David Norris and Luke Varney will resume in midfield, while Ross McCormack and Steve Morison will start again up front.
