Sam's place will be taken by Luke Varney, who will line up alongside Chris Iwelumo, but the defensive slots leave Pardew with interesting decisions to make.
Chris Powell should be fit after suffering concussion in the win over Ipswich, so Madjid Bougherra will take the centre-half spot, and youngster Yassin Moutaouakil will feature at right-back, where he started the season so brightly.
Possible side for West Brom: Weaver, Moutaouakil, Bougherra, Sodje, Powell, Ambrose, Zheng, Holland, Reid(C), Varney, Iwelumo
