Squad strengthened by return of Gilbey, Moncur and Healey.
Alex Gilbey (ankle) and Rhys Healey (appendix) have both been missing from the first team squad in recent weeks but are both named in the squad for the midweek clash against the Dons.
However, Sanchez Watt remains absent after their recent illnesses.
The U's have picked up ten points in their seven games in 2015 so far, and will be looking to extend that run when they take on Karl Robinson's side, who currently sit third in the League One table.
U's: Walker, Lewington, Hewitt, Briggs, Clohessy, Gordon, Vincent-Young, Eastman, Wynter, Harney, Fox, Moncur, Szmodics, Lapslie, Gilbey, Massey, Sembie-Ferris, McEvoy, Healey, Marriott, Porter
