Cheltenham defender Michael Hector is set to start after his loan spell from Reading was extended for a second month.
The 20-year-old has made seven starts for the club but could have a different centre-back partner against the Dons if veteran Steve Elliott fails a late fitness test on a knock picked up in Tuesday's 1-1 draw with Fleetwood.
If Elliott does not make it then Manchester United loanee Luke McCullough is likely to step into the side.
Full-back Sido Jombati is set for a recall as Cheltenham look to close the four-point gap between themselves and the automatic promotion places in npower League Two.
Young defender Harry Hooman is Mark Yates' only long-term absentee with a foot injury.
AFC Wimbledon will check on Jonathan Meades ahead of the trip.
The on-loan Bournemouth defender failed a late fitness test on an ankle injury ahead of Tuesday night's 1-1 draw against Plymouth.
With fellow full-backs Curtis Osano (calf) and Jim Fenlon (back) still missing, centre-half Mat Mitchel-King will deputise at right-back again if Meades is ruled out.
Midfielder Harry Pell suffered a gluteal injury in the pre-match warm-up against Argyle but managed to play the full 90 minutes and scored the Dons' goal, so he should be fine to continue.
On-loan Cardiff forward Jesse Darko is pushing for a full debut after coming on as a half-time sub.
Rashid Yussuff is a doubt through illness, fellow midfielder Peter Sweeney has a toe injury and defender Will Antwi a hip knock.
