Carlisle manager Greg Abbott is considering handing teenagers David Symington and Mark Beck their first starts for the club.
The youngsters have featured regularly off the substitutes' bench for the Cumbrians this season and Abbott is still without injured striker Lee Miller (knee).
Midfielder Liam Noble will sit out the second of his three-game ban following his dismissal in the recent Johnstone's Paint Trophy defeat to Preston.
Defender Danny Livesey remains doubtful due to the hamstring strain that has seen him miss the last four matches, while Abbott must decide whether to recall Adam Collin in goal or stick with youngster Mark Gillespie, who has started the last two matches.
Abbott has no new injury or suspension problems as his side chase their third league win of the season.
Swindon boss Paolo Di Canio may welcome back Troy Archibald-Henville.
The defender is closing in on a return to the Italian's starting XI after a knee injury but faces a late fitness test.
Matt Ritchie and James Collins both returned last weekend for the defeat to Leyton Orient and are expected to continue having come through the match unscathed.
Summer signing Gary Roberts is close to full fitness but may not be risked against the Cumbrians.
The midfielder is yet to make his debut for the Robins after suffering a leg injury in pre-season.
But now the former Huddersfield man is less than a fortnight away meaning Di Canio's side are almost back to full strength as they bid to end a three-match losing streak.
