Despite the loss Rotherham are still firmly in the play-offs places in sixth and, with games in hand on those around them, Evans is not panicking.
"I am not worried about seventh place," he said. "We just have to grind out and play our game. We don't appear to get decisions and sometimes that can be why you get promoted.
"I think that we have had a raw day from the official and when he looks back I'm sure he will be disappointed with his performance.
"I am not questioning his integrity, he's a very honest guy. We had a stonewall penalty ten minutes from time and any other week it's a penalty.
"Gillingham dominated us in the first half. They missed a couple of chances which could've sealed it and, after half-time, obviously they had a few more.
"But that was because we were pressing forward and having a little gamble so we've got to be disappointed that we pushed forward a lot and left with nothing.
"I don't know what the statistics will show in the second-half, but it will show a very, very high percentage of possession and chances."
