Two missing for Dons opener
Clark has a hernia problem which requires surgery, while Humphreys is nursing an Achilles injury.
Centre-back Sam Collins is expected to recover from an ankle injury to start, while summer signings Neil Austin and Jon-Andre Fredriksen have returned to training after knocks and are in contention.
Turner has been busy in the transfer market this summer, and fellow new-boys Scott Flinders, Peter Hartley, Leon McSweeney, Denis Behan, Adam Boyd and Steve Haslam could all feature.
Forward James Brown is fit again after a lengthy spell on the sidelines with a cruciate ligament injury but he is unlikely to be risked in the League One encounter at stadium:mk.
