Goalkeeper Manuel Almunia, who suffered an elbow injury, will miss Tuesday's Champions League match against Belgrade's Partizan.
The Spaniard, whose unreliable performance allowed West Bromwich players to score two goals against the 'Gunners' in the unsuccessful weekend English championship matches, will be replaced by Lukasz Fabianski.
Due to injuries, Cesc Fabregas, Theo Walcott, and Robin van Persie will also not take the field in Serbia, and there are doubts about full-back Kieran Gibbs as well.
