The left-back was forced off at half-time in last weekend's 1-0 defeat at Cheltenham and will now play no part against the Dons as the Gills go in search of the point which will crown them npower League Two champions.
Centre-back Leon Legge is only rated as 50/50 due to a hip injury and will hope to be involved at Priestfield, while Myles Weston (ankle) also continues to be assessed.
Already-promoted Gillingham are six points clear of second-placed Port Vale with two matches remaining and know any slip-up by the Valiants at home to play-off hopefuls Northampton will also be enough to seal top spot.
