Anthony Kay comes back into the reckoning for MK Dons.
Centre-half Kay has missed the last three matches through suspension following his third red card of the season against Crewe last month.
Captain Dean Lewington and striker Izale McLeod have resumed training after respective knee and hamstring injuries, although Dons boss Karl Robinson has yet to make a decision on whether their comebacks will be from the start or from the bench.
Winger Daniel Powell will be monitored after coming off against Crawley on Saturday, while goalkeeper David Martin is still struggling with the back injury that has kept him out for the past six weeks.
Luke Chadwick, Chris Lines, George Baldock and Alan Smith, all substitutes at the weekend, will all be eager to step in to replace Powell if required.
The goalless stalemate against Crawley left the Dons seven points adrift of the play-off places, prompting Robinson to say that his side must win all their remaining matches if they are to have any chance of sneaking into a top-six spot.
Swindon expect to have Andy Williams available for selection.
The 12-goal striker missed the 1-0 defeat to Doncaster with an ankle problem picked up against Oldham on Good Friday but could return for Kevin MacDonald's side as they look to record a first win in four games.
MacDonald remains without injured trio Nathan Thompson, Tommy Miller and James McEveley.
Defender Thompson may not feature again this season as the ankle injury that saw him miss the defeat to Doncaster is worse than first feared.
Fellow defender McEveley (knee) remains sidelined while midfielder Tommy Miller's calf injury rules him out of action, but he could be available at the weekend.
The Robins lie in sixth but could move up as high as third with a win.
