Veteran striker Jamie Cureton could make his debut for the visit of the Brewers.
The 37-year-old journeyman joined the Robins from Exeter earlier in the summer.
Fellow new arrivals Troy Brown, Ryan Inniss and Craig Braham-Barrett are available for selection at the back, while midfielders Matt Richards and Ashley Vincent could be named in manager Mark Yates' matchday squad.
Former Rochdale forward Terry Gornell could also make his first competitive start for the club.
The visitors will be without centre-half Zander Diamond when they begin their league campaign at Cheltenham.
Diamond could miss the opening month of the season after damaging a ligament in his foot during training so either Marcus Holness or summer signing Phil Edwards will partner Ian Sharps, who made his move to the Pirelli Stadium permanent over the summer, at the heart of the defence.
Striker Billy Kee could be fit for the big kick-off after battling a sore thigh in pre-season. He took part in a full training session on Wednesday and the club's medical staff are waiting to see if he suffers any reaction.
Veteran midfielder Rory Delap heads a list of nine new signings hoping to make their debuts for the Brewers, including on-loan goalkeeper Jordan Pickford, who joined on loan from Sunderland.
