Derby will assess Dean Leacock ahead of the visit of Leeds.
The centre-half made his first start for 13 matches against Coventry on Saturday as a makeshift right-back but was forced off with a painful bout of cramp midway through the second half.
With left-back Gareth Roberts still nursing a knee injury, manager Nigel Clough could be forced into another defensive reshuffle should Leacock not make it.
Theo Robinson staked a claim for a recall with an encouraging performance from the bench at the weekend after replacing Alberto Bueno, who looked tired against the Sky Blues.
Defenders Russell Anderson and Miles Addison and midfielder Stephen Pearson are options for Clough, who believes victory will be enough to secure his side's Championship survival.
Leeds pair George McCartney and Sanchez Watt could both return to contention following unspecified injuries.
Defender McCartney was replaced in the squad for Saturday's 3-2 defeat at Millwall by Paul Connolly and manager Simon Grayson must decide whether to recall the Sunderland right-back.
Grayson, who hopes to have a full-strength squad to choose from, switched Eric Lichaj, on loan from Aston Villa, to left-back at The Den.
Grayson also handed a first start to Jake Livermore, on loan from Tottenham, and he will be hoping to retain his place, while another loanee, Aston Villa's Barry Bannan, and Neil Kilkenny are pushing for recalls to the starting line-up in midfield.
Sixth-placed Leeds, who have lost three of their last four away matches, are four points clear of the chasing pack with six games left.
