Kay was criticised by manager Karl Robinson after two yellow cards in the space of five minutes late on in the midweek defeat to Crewe resulted in the centre-back's third dismissal of the season. He will now serve a three-match ban.
The absence of captain Dean Lewington (knee), wingers Luke Chadwick (hip) and Daniel Powell (hamstring) and goalkeeper David Martin (back) at Gresty Road meant Robinson could name only four substitutes against Alex.
Lewington and Chadwick will remain out while Powell and Martin are doubts along with strikers Dean Bowditch and Ryan Lowe, who are battling to be fit after sustaining injuries on Tuesday night.
Youth-teamers Dele Alli and Giorgio Rasulo have previously helped make up the numbers for the Dons this season but they are away on international duty with England Under-17s and Under-16s respectively.
Therefore, Robinson may be forced to call on other academy players, such as Brendan Galloway, to bolster his threadbare squad.
