Daniel Pudil is ruled out of Saturday’s trip to Birmingham after sustaining a facial injury at QPR in midweek.
Pudil was left with blood streaming down his face after receiving a boot to the face during the second half at Loftus Road and was immediately substituted.
Tom Lees, dropped to the bench at Rangers, is expected to replace Pudil and Jos Luhukay, who made five changes for that game, could switch things around again after the poor performance in West London.
Steven Fletcher is likely to get a start up front after coming on from the bench in midweek.
