Crystal Palace need at least a point to secure a playoff place, but a win would guarantee their place in the top six regardless of results elsewhere.
Peterborough are battling for survival and will be relegated if they lose and results elsewhere go against them.
Crystal Palace: Speroni; Ward, Delaney, Gabbidon, Moxey; Dikgacoi, Jedinak, Garvan; Zaha, Bolasie, Murray.
Peterborough: Olejnik; Rowe, Alcock, Zakuani, Bostwick; McCann, Payne, Pritchard, Mendez-Laing, Tomlin; Gayle
