West Ham's Arthur Masuaku could be out for several weeks after knee surgery.
Forward Michail Antonio looks set to remain sidelined by a hamstring problem while manager David Moyes said his squad had a "couple of knocks" that would also be monitored.
Crystal Palace defender Mamadou Sakho will be assessed ahead of the trip to West Ham United.
Jordan Ayew could be involved, having scored the winning goal in both Premier League meetings last season.
LAWRO'S PREDICTION
West Ham are playing really well at the moment. The players look lively in all areas - their work-rate is much improved - and, as well as that, they are very well organised too.
