George and Sam Baldock will go head-to-head this afternoon, with both players named in the starting line-up for their respective sides.
George will continue on the right-hand side of an attacking three for the Dons, a position he earned Man of the Match in two weeks ago, while his brother and former Academy striker Sam will lead the line for the visiting Robins.
Elsewhere, Karl Robinson makes just one change to the side that drew 2-2 with Preston North End, recalling talisman Luke Chadwick in place of 17-year-old Dele Alli who will start on the bench. Chadwick, who will start his first game since opening weekend this afternoon, will play alongside Baldock and Jason Banton and just behind striker Patrick Bamford.
Further back, Darren Potter and Stephen Gleeson will continue as the Dons’ midfield pairing ahead of a back four which remains the same from a week ago - Lee Hodson at right-back, Antony Kay and Jon Otsemobor at centre-back and Shaun Williams at left-back.
Ian McLoughlin, Alan Smith, Izale McLeod, Dele Alli, Samir Carruthers are the Dons' substitutes.
Dean Lewington (knee), Dean Bowditch (groin), Ben Reeves (ankle) and Daniel Powell (ankle) all miss out, along with defender Tom Flanagan, who suffered an injury in training this week.
