Crystal Palace will check on Claude Davis, Calvin Andrew and Alan Lee.
Davis (knee) has missed the last two games, while Andrew was involved in a clash of heads against QPR and Lee is nursing a groin problem.
One point and one place above the drop zone, Crystal Palace are looking to atone for an unexpectedly lifeless performance at home to QPR last weekend.
The Eagles' 2-0 defeat in that game did little to ease their relegation worries and they are heading for a nervous final-day match against the team immediately below them, Sheffield Wednesday.
Before that - and a game against promoted West Brom - Palace travel to face a Derby side that have kept a clean sheet in four of their last six matches.
Derby are not mathematically safe from the drop but their Championship status is all but secure after a run of only one defeat in seven matches. That loss was against Ipswich in their last match at Pride Park, for which they will be looking to make amends.
• Derby have not taken a point against Palace since beating them 1-0 at Pride Park in December 2006.

• They have drawn 10 away matches this season. Only Nottingham Forest have drawn more times away from home.
