Swindon forwards Keshi Anderson and Lloyd Isgrove are major doubts for the Sky Bet League Two clash with Northampton.
Anderson (knee) and Isgrove (dead leg) were injured in the weekend draw with Exeter and look unlikely to face the Cobblers, meaning Scott Twine and Adam May could come into contention to start.
Eoin Doyle scored on his debut at Exeter after arriving on loan from Bradford and will keep his place with fellow striker Jerry Yates serving the second game of a three-match ban for his dismissal at Colchester.
Teenage defender Dan Ballard’s loan spell from Arsenal was brought to a premature end following a serious knee injury.
Striker Vadaine Oliver is pushing for a start for Northampton.
Oliver came off the bench at half-time in Saturday’s defeat to Macclesfield and made an impact and could be recalled at the expense of Harry Smith.
Midfielder Alan McCormack is working his way back from a hamstring injury he sustained against Walsall on the opening day of the season but is unlikely to be risked.
Goalkeeper Steve Arnold is also sidelined with the hamstring problem so David Cornell will continue in goal and defender Reece Hall-Johnson remains a doubt with a knock.
