Bradley Johnson and Joe Ledley will be assessed ahead of Derby's home clash with Sheffield United.
The pair missed Saturday's 2-1 win at Ipswich with minor back injuries, with George Thorne and Tom Lawrence coming in.
Boss Gary Rowett made three other changes for the match, with Andre Wisdom, Johnny Russell and Sam Winnall starting.
Striker Winnall will almost certainly keep his starting spot after bagging a superb brace to earn the Rams the points at Portman Road.
George Baldock is set to start for Sheffield United.
Boss Chris Wilder had hoped to rest the defender for Saturday's game at Bolton but brought him on after 31 minutes for Cameron Carter-Vickers in a tactical switch.
Clayton Donaldson was also given a breather, with Billy Sharp starting, and the former Birmingham striker will hope for a more prominent role against the Rams.
John Fleck returned from suspension at the Macron Stadium and is likely to keep his place.
