Midfielder Jonny Howson could make his Norwich debut at Stoke tomorrow after finally returning to fitness from a knee injury.
Striker James Vaughan has picked up a hamstring problem which will delay his return from knee surgery, while full-back Marc Tierney (knee) is also out.
Centre-back Daniel Ayala (hamstring) trained this week, but may not be rushed straight into action. England under-21 defender Ryan Bennett has now joined up with his new club following a loan spell back at Peterborough.
Provisional Squad: Ruddy, Naughton, Ward, Whitbread, Drury, Pilkington, Fox, Johnson, E Bennett, Hoolahan, Holt, Steer, Crofts, Barnett, Morison, Surman, Wilbraham, Jackson, R Bennett, Ayala, Howson.
