Norwich defender Timm Klose will miss the visit of Preston with a hip problem.
Forward Marley Watkins (hip) will also be assessed, but midfielder Tom Trybull has already been ruled out with a back problem.
Defender James Husband served a one-match suspension for the midweek defeat at Nottingham Forest, but remains sidelined by a groin injury.
Alex Pritchard is closing in on a return following ankle surgery. Midfielder Alex Tettey (calf), forward Steven Naismith (ankle), defender Jamal Lewis (knee), midfielder Louis Thompson (Achilles) and winger Matt Jarvis (ankle) all continue their rehabilitation.
Preston midfielder Ben Pearson will be absent through suspension at Carrow Road.
Pearson serves a one-game ban after collecting his fifth yellow card of the campaign in the midweek victory at Bristol City.
John Welsh and Alan Browne are in contention to replace Pearson as North End manager Alex Neil prepares to return to his former club.
Long-term absentees Tommy Spurr (knee), Greg Cunningham and Sean Maguire (both hamstring) remain out, but Marnick Vermijl and Josh Earl could be in contention following their injury problems.
