Fulham have a full-strength squad available for the tie.
Matt Targett, who had to come off at half-time against Birmingham due to illness, is fit to play.
On-loan Sheyi Ojo will return to the squad after missing the last few games with an unspecified knock, while Floyd Ayite will be hoping for a start after a recent hamstring injury.
Fulham are favourites going into the play-offs but will be aiming for their first semi-final win at the seventh time of asking.
This will be the 62nd meeting between these two clubs in all competitions, with Derby winning 22 times (D20 L19). However, this will be first meeting between the two clubs in the play-offs.
Derby have lost just two of their last 12 home games against Fulham in all competitions (W7 D3).
However, Fulham did win their away league trip to Pride Park earlier this season, winning 2-1 in March with first half goals from Aleksandar Mitrovic and Ryan Sessegnon securing the points.
The side to finish third in the second tier has won promotion through the play-offs (current format) on 10 occasions (34%), more than any other position.
Fulham boss Slavisa Jokanovic said: “We have showed ambition, quality and self-belief many times in the regular season. Our season was fantastic and many teams want to be in the position we are. In the middle of December nobody believed we would be in the position to fight for the Premier League. We have three games ahead of us and we have great confidence. We must be ready to keep going and cross this line.”
