Midfielder returns from suspension.U's: Walker, Cousins, Olufemi, Wilson, Okuonghae, Eastman, Dickson, Garbutt, O'Donoghue, Bean, Bond, Gilbey, David Wright, Eastmond, Vose, Bonne, Szmodics, Morrison, Ibehre
Young duo Sammie Szmodics and Macauley Bonne are back in the squad after their FA Youth Cup exploits last week, but the U's will also be without Gavin Massey and Freddie Sears after recurrences of their injuries on Saturday.
The U's will, however, be without Cian Bolger, who has returned to parent club Bolton Wanderers after his month's loan came to a conclusion with the match at Deepdale at the weekend.
He missed the weekend game against Preston, where the U's picked up another valuable point, but will hope to force his way into the team for the midweek game against the Dons.
U's midfielder Craig Eastmond will be back and available on Tuesday night for the match against MK Dons, having served a one game suspension.
