Arsenal will be without forwards Lukas Podolski (hamstring) and Theo Walcott (calf) for their Premier League clash against West Brom at Emirates Stadium.
Defender Bacary Sagna (foot) is a major doubt, but Laurent Koscielny (thigh) is definitely out.
Full-back Andre Santos (stomach muscle) and midfielder Abou Diaby (thigh) continue their rehabilitation.
West Brom head coach Steve Clarke has virtually a full squad to choose from for the match.
Goalkeeper Ben Foster is the only absentee as he continues his rehabilitation work after undergoing a second groin operation, with Boaz Myhill again deputising.
Clarke has to decide whether to recall the likes of striker Peter Odemwingie and midfielders James Morrison and skipper Chris Brunt, who were rested for last weekend's encounter with Stoke.
Arsenal: Szczesny, Gibbs, Vermaelen, Mertesacker, Jenkinson, Cazorla, Rosicky, Wilshere, Arteta, Gervinho, Giroud, Mannone, Coquelin, Ramsey, Oxlade-Chamberlain, Chamakh, Arshavin, Djourou, Sagna.
West Brom: Myhill, Daniels, Reid, Jones, McAuley, Olsson, Tamas, Jara Reyes, Popov, Ridgewell, Yacob, Brunt, Mulumbu, Dorrans, Morrison, El Ghanassy, Gera, Fortune, Odemwingie, Lukaku, Long, Rosenberg.
