The Millers take on Fleetwood tomorrow, who know nothing less than a win will effectively end their play-off push.
Evans' men themselves are looking to build on Tuesdays 4-1 win over Exeter and gain another crucial three points in the automatic promotion race, so it could be an open game.
The gaffer said: "We felt really aggrieved after losing at Gillingham and Morecambe and the players were hurting.
"There's a football terminology that says you never change a winning team but if you look at the top teams they will do that if it is the right thing to do against that opposition. We have to concentrate on ourselves and we know we'll have a great backing on Saturday.
"We hope to give the fans the same level of performance that we did on Tuesday and Fleetwood will have to come and have a go after their defeat last week."
Evans welcomes back a host of players from injury, illness and suspension but may make minimal changes to his midweek line up.
