Skipper Jason De Vos has emerged as an injury concern ahead of Tuesday's trip to Wolves. The Canadian has a knee ligament strain and missed Monday training.
Town's head of sports science Dave Williams told the club site: "His knee is sore and we will have to see how he goes."
Richard Naylor is expected to take the armband if the 32-year-old fails to make it.
Irish midfielder Owen Garvan is once again omitted from the 18-man travelling party. Garvan has still been feeling the effects of his recent bout of shingles.
Scott Barron and Chris Casement are also left out, having been included in the initial 20 for Saturday's game with Crystal Palace.
Squad: Bowditch, Bruce, Clarke, Currie, De Vos, Forster, Harding, Haynes, Lee, Naylor, Parkin, Peters, Price, Richards, Sito, Supple, Williams, Wilnis.
