Allen watched his side claim their first point of the season at home to promotion favourites Brentford last weekend and it would have been all three had it not been for an equaliser in the fifth minute of injury time from the visitors.
Chris Whelpdale and Adebayo Akinfenwa were brought in to Allen's XI to face the Bees following a 4-0 defeat at Wolves and the pair will be looking to retain their places.
Midfielder Amine Linganzi (hamstring) is again doubtful to feature while right-back Matt Fish has started out on his long road to recovery having undergone knee surgery last week.
