The visitors twice hit the post in the first half with Sam Winnall shaving the outside of the upright and Terry Hawkright crashing his25-yarder against it with keeper Steve Mildenhall at full stretch.
Rovers also needed a goal-line clearance from defender Michael Smith, who denied Winnall again, to keep themselves in a contest in which visiting keeper Sam Slocombe did not have a serious save to make.
Already missing 10 players through injury, Rovers had their ranks depleted further when they lost skipper and central defender Tom Parkes who departed on a stretcher in the 17th minute after being knocked unconscious while tussling with striker Deon Burton.
Scunthorpe created the better chances after the break but Mildenhall tipped over Burton's glancing header and Hawkright twice went close, firing wide from a 25-yard free kick before scooping over the top from 14 yards.
