Karl Robinson is expected to reveal who his new assistant manager is when Dons return for pre-season training later this month.
Mick Harford left the club on Tuesday after speculation had gathered pace at the weekend, with some reports suggesting he had been sacked.
The 54-year-old took over the job last May after popular John Gorman announced his retirement in 2012.
Neither Dons or Harford have been willing to go into much detail about the reasons behind his departure.
In Harford’s 13 months at stadium:mk, it’s hard to look past the results – Dons failing to make the play-offs for the first time since Robinson took over.
Some fans, particularly in the early stage of the season, pointed the finger at Harford’s influence over the side.
Known as something of a no nonsense hard man, the former Luton Town manager’s personality was perhaps too much of a shock to the system for the Dons players.
Robinson hinted before the season had finished that he would be making changes to his backroom staff this summer.
Ian Wright was announced as first team coach alongside Harford, but Robinson insists his role will remain part-time next season as he continues to host his Absolute Radio show on Saturdays.
He said in April: “There will be changes to the backroom staff, but it wouldn’t be right to talk about them yet. It’ll be based on a continental system with heads of department.”
Dons return to pre-season training on Monday, June 24, when Robinson is expected to announce at least one addition to his staff.
Former Wycombe boss Gary Waddock is reported to have been offered a role. The 51-year-old has been out of work since leaving the Chairboys last September.
