Within minutes a further change was enforced as eighteen year old Alex Finney came on for his debut at hooker with Andy Morris having to move to prop.
Scouts were dominant without scoring in the first quarter although Adam Frost eventually notched a penalty to take the lead. The visitors began to slip into gear and their abrasive forwards drove them up the field and following several drives at the line they crossed for a seven pointer near to the end of normal time.
With several stoppages an extra fifteen minutes were added to the half and Frost kicked two penalties to nudge Scouts ahead before Rasen grabbed the lead with a pen of their own.
After the break Frost slotted his fourth penalty to put Scouts back into the lead and with five minutes left a scintillating break by centre Liam Hancock saw him stopped five metres short. Dean Lake was in support and picked up to dive over and with Frost converting Scouts were two scores ahead.
Again there was plenty of injury time which meant the hosts had to hang on for a further ten minutes and went down to fourteen with uncontested scrums.
The visitors battered Scouts line but resolute defence held out to only give away a penalty and the final whistle was a welcome relief.
