Mark Crossley is fighting to get fit for Saturday's big clash with promotion rivals Leicester City. He had to retire from the 4-0 victory over Hereford when he went down with back trouble.
John Sheridan said, "He was struggling and we'll have to see how it goes. Hopefully it won't be too serious."
Centre-half Sean Gregan will also be back in contention for a starting place in the team after serving a three-match ban for his sending off at Hartlepool.
