The 19-year-old, on a season-long loan from Norwich, has returned to his parent club for treatment after being forced out of Friday night's defeat at Southend due to a thigh injury.
Interim manager Peter Jackson said: "Tom picked up a thigh strain during the game on Friday and will be returning to Norwich for a week to receive treatment.
"He'll be missing for Tuesday and should be out for around two weeks with it."
