After many rumours, the ex-Exeter boss, Paul Tisdale, has been confirmed as manager.
The 45-year-old succeeds Keith Millen who was in charge for the last 3 games.
MK Dons face life in League Two this season after being relegated with a record-low amount of points.
Dons fans will be pleased that Chairman, Pete Winkelman, has gone for experience with Tisdale having spent 12 years at his previous club, taking Exeter City to the play-off final at Wembley last week.
