Evans' side are looking to close the gap on the top three whilst the Millers are out for revenge for the 2-1 defeat in the reverse fixture back in November - a game they largely dominated.
The Crawley boss spoke to their official website, and warned of Rotherham's dangers.
"Our next challenge is a Rotherham side who are very decent with a number of very good footballers. They won on Tuesday night, it has to be said relatively comfortably, and will be a real threat.
"Rotherham will be motivated to beat us, all teams in League 2 are. This will be as hard a game here at the Broadfield as we've had all season. Our opponents are a very big club in League 2, they have a superb chairman in Tony Stewart and they will bring a support with them that as usual will be loud and proud. We have to be ready to meet their challenge head on, they will be very dangerous opponents given the quality of player they have.
"We will have to work smart and perhaps at times we're going to have to be patient. So are our supporters."
