Anthony Tonkin is rated as 50/50 as Aldershot aim to end their miserable six-match losing streak.
The defender missed last weekend's 4-0 defeat at leaders Gillingham with a knock and is facing a battle against time to be fit for the visit of the Millers.
Long-term absentees Ross Worner (back) and Craig Stanley (broken leg) continue to make progress ahead of their scheduled returns.
Otherwise, manager Dean Holdsworth boasts a fully-fit squad, with 20-year-old striker Reece Connolly on Wednesday recalled from his loan spell at non-league Farnborough.
Holdsworth made four changes at Priestfield last weekend, with midfielder Danny Rose coming in for his debut, and it remains to be seen how he will go about stopping the rot against a Rotherham side who have not won away from home all season.
The clash is Aldershot's first on home soil since they were booed off in the aftermath of their 1-0 defeat to Chesterfield.
Rotherham boss Steve Evans will make changes when his side go in search of their first away win of the season.
The Millers, who were beaten 3-0 by Southend last weekend, welcome back Kari Arnason from international duty unscathed, so the Iceland midfielder will go straight back into the starting XI.
Evans has revealed that one "key player" will miss out with an injury sustained in training on Tuesday, but opted not to reveal his identity.
Striker Alex Revell has completed a three-match ban and will hope for a recall in attack alongside Kayode Odejayi, while Daniel Nardiello will also hope to be included.
Evans, who returns to the dug-out having completed his six-match stadium ban handed down by the FA, could make other changes after admitting last week's loss to Paul Sturrock's men made him feel "physically sick".
The Millers are yet to taste success on the road this term having drawn three and lost two of their five outings.
