Rotherham United made it three league and cup games unbeaten after a goalless draw at near-neighbours Doncaster Rovers.
The Millers recorded their third consecutive clean sheet in an entertaining draw at Rovers' Cantley Park training ground.
The Millers best chance fell to striker Kuda Muskwe whose strike just before half-time was pushed away at full stretch by Rovers stopper Jack McLaren.
