The two sides are currently level on points and occupy the two places above the relegation zone with five matches of the season remaining.
But the bare facts disguise that Forest are in freefall with just a solitary point from their last six matches while Rotherham are resurgent under new manager Neil Warnock.
Much-travelled and sometimes controversial he may be but Warnock's side have taken twenty points from a possible twenty four during an eight-match unbeaten run that has made them odds-on to retain their Championship status.
The latest of those games was a 4-0 victory at MK Dons that also did Forest a favour by keeping the gap between Milton Keynes and safety at nine points.
Former Reds Lee Camp, Greg Halford and Matt Derbyshire all started last weekend's game and they will all be relishing meeting their old club this coming Saturday.
