Walsall have no new injury concerns and could well be unchanged after two memorable away wins inside a week at Crewe and local rivals Wolves.
Saddlers boss Dean Smith's only decision appears to be whether to keep faith with his new-look 4-5-1 system at home against the in-form Millers.
Rotherham are unbeaten in seven games, but have defensive worries. They will be without Claude Davis (hamstring), whilst the recovering Craig Morgan (ankle) is a slight doubt and midfielder Michael O'Connor (groin) is definitely out.
Boss Steve Evans is hopeful of sealing the loan deal for Bolton striker Tom Eaves in time to feature in his squad.
Having picked up successive away clean sheets, Walsall have conceded just six goals in seven league games - a record bettered in League One only by leaders Leyton Orient, whilst the visitors have hit six goals in the space of a week, beating neighbours Sheff Utd and then Oldham on their own patch.
