Robin van Persie will return to the Arsenal starting line-up.
The Holland international was named as a substitute for the midweek 0-0 draw against Marseille in the Champions League, although manager Arsene Wenger has confirmed he will start against the Baggies.
Wenger expects to name the same squad used against Marseille and is without Marouane Chamakh (knee), Kieran Gibbs (stomach), Abou Diaby (hamstring), Jack Wilshere and Bacary Sagna (both ankle).
West Brom midfielder Paul Scharner has been ruled out of the game with a knee ligament problem which flared up during last weekend's home defeat against Liverpool.
Manager Roy Hodgson will check on the fitness of striker Peter Odemwingie, who suffered a knock to his knee in training this week, before finalising his side.
But Odemwingie's strike partner Shane Long is again unavailable with the knee injury sustained against Aston Villa a fortnight ago.
