Defender Paddy McCarthy had to be substituted with a knock at the Madejski Stadium and will have a late fitness check, but winger
John Oster is expected to shake off a thigh strain.
Tom Soares' deadline-day switch to Stoke could pave the way for Ben Watson to make his first league appearance of the season.
The wantaway midfielder had been frozen out by manager Neil Warnock, but with the transfer window closed he may now find himself back in favour.
Swansea defender Marcos Painter is a slight injury concern ahead of the trip.
Painter signed a new long-term deal with the Swans on Thursday and has been able to train this week despite being hampered by a minor ankle problem.
Boss Roberto Martinez expects to have Painter at his disposal against the Eagles and is also boosted by the return to fitness of left-back Federico Bessone.
Bessone has recovered from a fractured rib and could come into contention as Martinez's men bid to extend their unbeaten streak in all competitions to six games.
Midfielder Ferrie Bodde has scored two goals in his last three outings and will be hoping to extend his purple patch in front of goal this weekend.
