Roberts (hip) and Pogrebnyak (unspecified) are doubtful for the game at the Madejski Stadium but may play some part. Jimmy Kebe (groin) and Jem Karacan (knee) have returned to training but will not play, while Sean Morrison (ankle) is still sidelined and Alex McCarthy is out long term. Arsenal should have striker Olivier Giroud in contention again following a back problem for the trip to Reading. Defender Laurent Koscielny has resumed training after his thigh injury, but England winger Theo Walcott (calf) will be assessed. Full-back Andre Santos (stomach muscle) and midfielder Abou Diaby (thigh) continue their rehabilitation.
