Burnley are hopeful Dwight McNeil and Robbie Brady will be available after they missed Sunday's defeat at Leeds.
Matej Vydra, Jack Cork and Johann Berg Gudmundsson are back in training but Clarets boss Sean Dyche has intimated the game will come too soon for them.
Sheffield United are assessing Oliver Burke and Oli McBurnie with respective back and shoulder issues.
John Lundstram remains suspended and joins fellow midfielder Sander Berge as certain absentees.
