Bowditch and Powell have returned to training following groin and ankle injuries respectively. Both players are listed as doubts for the trip to London Road but manager Karl Robinson has hinted that, if all goes well, they could feature on the bench.
Once those two return, the Dons will have a fully fit and available squad.
Saturday sees the first meeting between Peterborough and MK Dons since May 2011 when Posh edged a thrilling League One play-off semi-final 4-3 on aggregate. A defeat, the manner of which, Robinson this week admitted still angers him.
