Sheffield United goalkeeper Mark Bunn is the latest to fall under the Bramall Lane injury curse this season and is expected to miss the league game at Preston.
Bunn sustained an injury to his thigh and a possible broken finger in the weekend draw with Derby and was replaced by Ian Bennett, who is on stand-by.
Skipper Chris Morgan is still sidelined after tearing a rib muscle in last week's defeat at Watford and Marcel Seip (hamstring) is not ready to return.
But manager Kevin Blackwell can call on defender Andy Taylor, who has been out with a hamstring strain.
James Harper (ankle) and Gary Naysmith (knee) are still out, so Blackwell will have to deploy some players out of position again.
Regulars midfielders Jordan Stewart and Nick Montgomery were both forced to start as full-backs against Derby.
