The right-back, on loan from QPR, faces a number of weeks on the sidelines but would have missed the clash in any case due to his international commitments with the Republic of Ireland's Under-21 side.
That means manager Martin Allen will be forced to change a winning formula as the Gills aim for a third successive triumph.
Allen kept faith with the same XI who recorded Gillingham's first win of the season at the 11th attempt as they beat Crewe 3-0 and duly watched his unchanged side make it back-to-back victories against MK Dons last weekend.
