Dominic Green was handed his first start since last May at the weekend in place of former captain George Boyd, who was making his debut for Nottingham Forest after sealing a loan move last week.
Left-back Scott Griffiths is starting a spell on the sidelines with an adductor muscle strain so Tommy Rowe will fill in again, while club-record signing Ryan Bennett remains out.
Bennett has missed the last two games with an ankle injury and could be out for at least another fortnight but fellow defender Gabriel Zakuani is back from a groin strain.
The match kicks off at 7.30pm.
