The home side double their lead!
Ollie Rathbone lashes a thumping shot at goal from 25 yards out that thunders off the underside of the crossbar and, after a few moments of uncertainty, is deemed to have crossed the line.
The Millers pressed up high and forced mistakes from the Rovers defence and ultimately got their reward.
No changes at the break from either side.
Blackburn will be happy enough with how the first 45 minutes went really but they're going to have to find a cutting edge if they're to get back in this.
