Lee Hodson, Samir Carruthers and Tom Flanagan all return to contention for the Dons ahead of this weekend's outing.
The trio missed the home draw with Swindon last weekend. Hodson and Carruthers were away on international duty with Northern Ireland and the Republic of Ireland Under-21 side respectively, while Flanagan was nursing an ankle injury.
All three players face competition if they are to force their way back into manager Karl Robinson's starting XI. In Hodson's absence, Jon Otsemobor has performed well at right-back while loan duo Jason Banton and Danny Green have impressed on the wings.
Daniel Powell (ankle) and Dean Bowditch (groin) remain sidelined through injury. The latter returned to training this week while Powell is still in the early stages of his rehabilitation.
The Magpies will check on a handful of players before they travel to Milton Keynes to face the Dons.
Notts County were without a game last weekend due to international call-ups which meant more time for the likes of Alan Sheehan (hamstring), Enoch Showunmi (back), Haydn Hollis and Danny Haynes to recovery from their injuries. However, it is still unclear whether they will be fit in time for Saturday's game.
Manager Chris Kiwomya will need to decide whether to keep Manny Smith at the heart of defence and last year's player of the year Gary Liddle in midfield.
Striker Marcus Haber and 18-year-old forward Jack Grealish are available to make their debuts having arrived on loan from Stevenage and Aston Villa respectively on Friday.
