Skipper Adel Taarabt has been suffering with stomach cramps recently, but still managed 70 minutes of Tuesday night's 1-0 win at Barnsley.
The midfielder, who took his goal tally for the season to 16 with the first-minute winner, was taken off as a precaution but will be fit to face the Rams.
Recalled centre-half Matt Connolly should have done enough to keep his place ahead of Dan Shittu and Fitz Hall.
Full-back Peter Ramage played for the reserves this week after seven months out with a cruciate injury, but will not be considered yet.
Striker Jamie Mackie is still recovering from a broken leg.
