Striker Shaun Harrad plays the final game of his loan deal from Bury, but was named a substitute. Defender Richard Naylor (knee) missed out but winger Gareth Evans was back after nearly two months on the sidelines with a back injury.
The Millers finally broke the deadlock with 20 minutes remaining, when Lewis Grabban converted from the penalty spot.
