The Millers have been undefeated in their last three encounters, collecting seven points which have propelled them right back into play-off contention.
Scott hinted he would be tempted to freshen things up following Saturday's 1-1 draw at Burton, with on-loan striker Shaun Harrad one player who could be struggling with fatigue.
But Scott would be loathe to drop Harrad, with the Bury man scoring three goals in his first three appearances in a Millers shirt, though 15-goal top scorer Lewis Grabban will be chomping at the bit to return to the starting XI.
Midfielder Danny Schofield will return to the squad after missing the trip to the Pirelli Stadium with a tooth problem, meaning Gareth Evans (back) and Luke Foster (knee) are the only occupants of the treatment room.
The Millers have a dreadful record at the Priestfield, having not won on their last nine visits, a run stretching back to 1988.
