Midfielder Dean Marney and forward Martin Paterson came off during the New Year's Day win over Sheffield Wednesday with thigh injuries and will be assessed.
Top scorer Charlie Austin is absent with a hamstring strain, while winger Junior Stanislas is pushing to return from a similar complaint.
If Stanislas does not recover in time it could pave the way for Dane Richards to be involved, providing international clearance can be rubber-stamped following his pre-arranged new year move to Turf Moor from Vancouver Whitecaps.
Defender Ben Mee remains on the sidelines with strained medial knee ligaments.
