Ross Wallace faces a three-match ban following his sending off against MK Dons.
The winger was shown a straight red card for violent conduct and that means he is set to miss the final three league games – at Derby on Saturday, at home to Cardiff and then the final match at Wolves.
Assistant manager, Lee Bullen, also says it is likely Jeremy Helan will be recalled from his loan spell at Wolves, replacing loanee Joe Bennett who is ruled out for the rest of the season through injury.
