Norwich expect to have Scotland winger Robert Snodgrass available following concussion for Saturday's Barclays Premier League clash against West Ham at Carrow Road.
Midfielder Nathan Redmond is a doubt because of a hip problem, while record-signing Ricky van Wolfswinkel remains out with a foot injury.
Midfielders Alexander Tettey (ankle) and Elliott Bennett (knee) are both long-term absentees.
Provisional Squad: Ruddy, Martin, Turner, Bassong, Olsson, Snodgrass, Howson, Johnson, Fer, Pilkington, Hooper, Bunn, R Bennett, Hoolahan, Garrido, Becchio, Whittaker, Josh Murphy, Elmander, Redmond.
West Ham will be without defender Winston Reid for their Barclays Premier League trip to Norwich on Saturday evening.
The New Zealand international suffered an ankle injury in training and will not be fit in time for the clash at Carrow Road, although fellow defender James Collins is available following a hamstring complaint.
The Hammers' forward options remain limited with Andy Carroll (heel) and Mladen Petric (thigh) both ruled out while Matthew Taylor (thigh), George McCartney and Alou Diarra (both knee) are also absent.
Provisional Squad: Jaaskelainen, Adrian, Demel, O'Brien, Rat, Collins, Tomkins, Potts, Ruddock, Diame, Nolan, Noble, Collison, Downing, J Cole, Morrison, Jarvis, Maiga, C Cole.
