Norwich midfielder Wes Hoolahan could make his first league start of the season against QPR.
Hoolahan missed several weeks of pre-season training due to a thigh problem and has started both Championship fixtures on the bench.
Josh Murphy is also pushing for a start, while boss Daniel Farke is expected to select from an unchanged squad, with no new injury worries following Sunday's home defeat to Sunderland.
Defender Timm Klose is still working his way back from a leg muscle problem and Alex Pritchard is recovering from ankle surgery.
QPR manager Ian Holloway will resist the temptation to recall Steven Caulker to his first-team squad too early.
