Lewington suffered a knee injury as the Dons got their League One campaign under way against Shrewsbury last weekend and missed the Capital One Cup tie at Northampton on Tuesday night. The left-back will undergo a fitness test ahead of the game.
Daniel Powell, however, will definitely not feature. The winger faces more than two months on the sidelines after damaging ankle ligaments last week in a training match.
Dean Bowditch also remains out of action, although the forward's groin complaint should not rule him out for too much longer.
