Rovers pair return with problems
Blackburn are expecting to be without Simon Vukcevic and Fabio Nunes for the trip to Derby after the duo picked up injuries on international duty.
Montenegro international Vukcevic returned to Rovers' Brockhall training base with a groin problem while winger Nunes suffered a hamstring strain when playing for Portugal Under-21s.
Martin Olsson also suffered a mishap while representing his country, going down with food poisoning while away with Sweden, but the full-back is expected to be fit to face the rams.
Striker Jordan Rhodes and defender Grant Hanley returned early from the Scotland set-up with respective ankle and groin injuries but are also set to feature.
Markus Olsson (hamstring) remains on the sidelines, but caretaker boss Eric Black, searching for a first win at the helm in his fourth match, said: "Markus unfortunately is still out 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."
