The Republic of Ireland defender was rested for Tuesday night's 2-0 FA Cup third round replay defeat by Bolton after complaining of tightness in his hamstring, while the Scotland striker missed out through illness, but both are expected to return.
Defender Kader Mangane and midfielder Alfred N'Diaye could be included after being ineligible in midweek, although the former is short of match-fitness, but skipper Lee Cattermole is likely to miss out despite returning as a substitute against Bolton after aggravating his knee problem.
