With Izale McLeod cup-tied, the 32-year-old boss hands striker Alan Smith a start as the lone striker, with the rest of the side that earned a 0-0 draw at Doncaster Rovers on Tuesday remaining as they were.
Luke Chadwick continues in the middle of an attacking three with Dean Bowditch and Daniel Powell either side of him, while Gary MacKenzie shakes off an ankle knock to partner Shaun Williams at the heart of the Dons defence.
Darren Potter and Ryan Harley will be the midfield two while Jon Otsemobor and Dean Lewington remain the Dons’ full-backs.
On the bench, there are places for young trio Brendan Galloway, Giorgio Rasulo and Dele Alli, the latter having returned from a stint with England Under-17s earlier this week. Defender Tom Flanagan awaits his first appearance of the season, he is amongst the replacements. Midfielder George Baldock is cup-tied.
