The Scot enjoyed the perfect start to his managerial reign as his new side ran out 2-1 winners at Coventry thanks to a couple of late goals and MacDonald could stick with the same XI as they look to return to the automatic promotion places.
Luke and Adam Rooney both played vital parts in the late turnaround last Saturday and the pair are likely to be involved again at The County Ground.
Striker Miles Storey and defender Troy Archibald-Henville remain out but otherwise MacDonald has the same squad to select from.
Swindon, who ran out 2-0 winners when the sides last met back in November, are two points behind second-placed Sheffield United.
