Henderson scored his second just at the start of the second half to push the Scots 24-6 clear but the Irish rallied and tries from Andrew Trimble and Isaac Boss and a monster penalty from Paddy Wallace left just three points separating the sides with ten minutes to go.

Then however, the Lamont brothers combined to set up a five metre scrum and from that Henderson burst over under the posts
