Miller has made seven changes to the side that lost to England in our festival opener last week.
Oliver Anderson comes into the starting front row at tighthead prop. Logan Hendrie starts at loosehead prop once more, and Jack Utterson continues at hooker.
Captain Christian Lindsay is paired with Will Lockhart in the second row, and the forwards are completed by Harry Jackaman at blindside flanker, Harvey Preston at openside and Dan Casserly at number eight.
The half-back pairing is made of Gregor Johnston at scrum-half, and Ben MacDougall starting at stand-off.
In the centres, Harry Clark begins on the inside and is joined by Will Corbett on the outside.
Ben McDonald is selected at left wing, with Luca Mathieson on the right. Full-back David Barrie completes the starting team.
