Swindon will be without goalkeeper Phil Smith for the clash with Hereford.
The former Crawley stopper picked up a groin strain during the 2-0 defeat at Macclesfield last Friday and has been ruled out for up to three weeks.
Mattia Lanzano will deputise in between the sticks once again for the Robins, but manager Paolo Di Canio has already stressed he wants to bring in another keeper on loan as cover.
Midfielder Oliver Risser returned to the first team as a second-half substitute in the 2-1 win at Exeter in the Johnstone's Paint Trophy in midweek, and the Namibian may well be included in the squad to face the Bulls.
After scoring twice on his full debut in the same game, on-loan striker Jake Jervis will keep his place up front, with either Mehdi Kerrouche or Alan Connell partnering him. Midfielder Abdul Said is a long-term casualty for Swindon with a leg injury.
Hereford will be without David Cornell and Delroy Facey for the trip but Steve Leslie is in line to make his second debut for the club.
On-loan Swansea goalkeeper Cornell and striker Facey are away on international duty with Wales` Under-21s and Grenada respectively and miss out at the County Ground.
Cornell`s absence provides a problem with Adam Bartlett still sidelined with his thigh injury, meaning assistant manager Russell Hoult, who made his name with Derby and West Brom, is set to step in between the sticks.
On-loan striker Nathan Elder will compete with Yoann Arquin to replace Facey in attack having made his Bulls bow as a half-time substitute in last weekend`s 1-0 home defeat to Oxford.
Winger Leslie returned to Edgar Street on a month`s loan from Shrewsbury this week having spent the final two months of last season with the club.
He comes into contention along with fellow on-loan midfielder Simon Clist, who was ineligible to face parent club Oxford under the terms of his deal.
