The home side had a shaky start to the season under new manager Matthew Taylor, having to wait four games before their first three points of the season.
Walsall will be without key man Liam Kinsella, who is undergoing knee surgery after picking up an injury against Newport County.
Rollin Menayese may have a chance to feature against his former club, after previously having a spell with the Gas between 2017 to 2020.
The Gas' problems don't end there, with their treatment room currently stacked. Sam Nicholson (shin), Trevor Clarke (groin), Alex Rodman (illness) and Luca Hoole (calf) will all likely be missing too.
James Belshaw may start against the team he began his career at.
Walsall: Rushworth; White, Menayese, Monthe, Ward, Phillips, Perry, Earing, Shade, Osadebe, Miller
Bristol Rovers: Belshaw; Grant, Kilgour, Taylor, Anderton, Brown, Finley, Whelan, Evans, Collins, Pitman
Ones to watch
A hungry forward who has had a great start to his career with Walsall, Miller's loan arrival has been a breath of fresh air for the Saddlers.
With two goals in his opening three games, Miller netted twice to help Walsall mastermind a victory over Mansfield Town. The forward has brute pace and is composed in front of goal, and despite struggling for Scunthorpe United last season, Miller has a big chance to establish himself in League Two this year.
Despite not netting his first goal of the season yet, Evans has looked bright in his opening few games for Bristol Rovers.
The midfielder was in Sky Bet League One last season and in the German second division the year before that, so the attacking playmaker boasts experience of a higher level of football. With attackers like Brett Pitman and Aaron Collins ahead of him, Evans should start boosting his stats pretty soon.
