Bristol City captain Louis Carey will be assessed ahead of the trip to Derby.
The defender only recently returned following a fractured skull and boss Keith Millen `remains concerned` about the 34-year-old.
Should Carey not be risked, James Wilson could make his first Championship start.
Millen is considering giving reserve goalkeeper Dean Gerken a run-out in one of the final two matches this season. The move would end David James` ever-present record in the league this season.
Academy product Bobby Reid has been included in the squad for the first time and could make the bench.
Defender Damion Stewart and midfielder Kalifa Cisse remain on the sidelines through injury while striker Nicky Maynard is still suspended.
