Chris Porter could return to the Derby starting line-up when Crystal Palace visit Pride Park.
The striker`s run of five successive starts came to an end at Barnsley last weekend when an ankle injury meant he was only fit enough for the bench.
The 26-year-old, who was absent for the first four months of the season with a troublesome hip problem that required surgery, has trained this week.
Boss Nigel Clough said: "He did it last Friday but it has settled down a lot since then. It was just precautionary to leave him out at Barnsley. He was on the bench and if the ankle was that bad we would not have included him at all.
"He is keen not to miss any of the last three games after missing much of the season."
Dean Moxey, Gilles Sunu and Gary Teale are also pushing for recalls but Stephen Pearson remains unavailable as he completes a two-match suspension. Kris Commons continues to battle his way back from a hamstring injury.
Palace will check on Claude Davis, Calvin Andrew and Alan Lee ahead of the trip.
Centre-back Davis has missed the Eagles' last two games due to a knee injury but could return at Pride Park.
Andrew was on the other end of the clash of heads which left QPR defender Damion Stewart with a fractured skull on Saturday and has been monitored all week.
Fellow striker Lee aggravated a groin problem against Rangers and is still struggling.
Palace's injury problems have eased slightly, however, after full-backs Danny Butterfield and Nathaniel Clyne returned to action last weekend.
Butterfield has been sidelined for three weeks with a hamstring problem and Clyne has shaken off a hip injury.
