Boss Gary Waddock is without striker Paul Furlong (thigh) for the match, while Kevin Gallen and Marc Nygaard are still struggling with injuries picked up during pre-season.
Their absence means Rangers are likely to stick with the 4-5-1 formation they used in the 2-0 defeat at Burnley, with summer signing Adam Czerkas operating as a lone striker.
Midfielder Egutu Oliseh is set to miss out with a thigh injury, and defender Dominic Shimmin serves the second game of a three-match ban.
