Vukcevic returned with a groin problem while winger Nunes suffered a hamstring strain.
There was also a slight scare with Martin Olsson, he suffered food poisoning while away with Sweden. However, after an examination it seems that he will be okay to take his place in the side at Pride Park.
Striker Jordan Rhodes and defender Grant Hanley both returned from their adventures with the Scotland set up with ankle and groin injuries respectively, but again, both should be fit for the trip.
And as far as Markus Olsson goes, caretaker manager Eric Black has said: "Markus unfortunately is still out (hamstring) so he won't be travelling with us. But we are hopeful in the next 10-12 days that he might re-join the group."
