Derby will check on leading scorer Jamie Ward and midfielder Craig Bryson ahead of the visit of Ipswich.
Ward, who netted his 12th goal of an injury-interrupted season during the 3-0 home win over Bristol City last Friday, missed Monday's victory over Leeds with a tight hamstring while Bryson was forced off at Elland Road after 34 minutes due to a groin problem.
Rams boss Nigel Clough will make a late decision on both players.
He said: ``Hopefully, they will be okay. We will leave it as late as possible with them. We'll leave it until Friday, even Saturday morning to see how they are. They are important for us and we want them out there if possible.''
Craig Forsyth's loan from Watford has been extended. His initial deal expired after the Leeds game but the midfielder will now remain at Pride Park for the remainder of the season.
The player, 24, will probably continue to deputise at left-back if Gareth Roberts misses a fourth match with his calf problem.
David McGoldrick will make the final appearance of his loan spell when Ipswich travel to Pride Park.
McGoldrick joined Town in January on a maximum 93-day deal from Nottingham Forest with a view to a permanent switch in the summer - a move which is still set to go ahead.
However, his loan arrangement expires after the trip to Pride Park, when the striker will briefly return to Forest.
McGoldrick is one of a handful of players pushing for a recall to manager Mick McCarthy's starting XI.
Having bagged a brace in the 3-0 victory over Leeds last Saturday, McGoldrick was rested to the bench for Monday's goalless draw at Millwall as McCarthy rang the changes, also leaving out Jay Tabb, Carlos Edwards, Daryl Murphy and Andy Drury.
Each of the quintet will be aiming to return to the fold at Derby, where boss McCarthy is not expected to have any new injury or suspension concerns.
