Defender Coughlan missed the QPR win with a slight hamstring niggle as well as having a virus so he will hope to return after a fitness test.
Burton meanwhile came off against Rangers at half time because he was struggling with a calf strain and like Coughlan, he will undergo a late test to see if he is healthy to play.
Caretaker manager Sean McAuley has no other problems to worry about although he will not be able to call upon Barry Corr - he was shipped out on loan to Bristol City yesterday for a month in a bid to increase his match fitness.
