Chris Martin has missed out on a place in the Derby County squad to face Blackpool after aggravating a hamstring injury.
The setback for the forward has forced Steve McClaren into one of four changes to the side as Ryan Shotton, Zak Whitbread, Simon Dawkins and Jesse Lingard all return to the starting lineup.
However, there is still no Will Hughes, who serves the second half of his two-game suspension.
Lee Clark has been handed a boost with the news that Darren O'Dea has recovered from an injury concern to keep his place in the Blackpool defence.
The admirable performance in Saturday's loss to Ipswich Town has persuaded Clark to resist making changes as his relegated side look to find form at the end of a disappointing season.
Derby: Grant, Bryson, Keogh, Dawkins, Hendrick, Lingard, Whitbread, Ince, Shotton, Warnock, Bent
Blackpool: Parish, Maher, Clarke, O'Dea, Dunne, Cubero, O'Hara, Perkins, Orlandi, Cameron, Madine
