The midfielder failed a late fitness check on an ankle problem ahead of Saturday's 1-0 win over relegation rivals Sheffield United and will be assessed before kick-off.
South Africa international Kagisho Dikgacoi impressed on his debut at the weekend after joining on loan from Fulham and should keep his place in the centre of midfield.
Nathaniel Clyne is playing despite an ongoing knee problem which has restricted his training and he should be okay to continue, but fellow full-back Lee Hills remains a long-term absentee with a knee injury.
The Eagles are also poised to complete the signing of 17-year-old midfielder Quade Taylor from non-league Dulwich Hamlet.
