Luke Hamilton has been named in a 33-man Scotland squad for their summer Tests.

The Leicester Tigers back row, who won his first cap in the autumn Test against New Zealand, is joined in the squad by Leicester-bound David Denton as the Scots prepare for tour fixtures against Canada, USA and Argentina.

Leicester Tigers prop Sam Grahamslaw has also been named in the Scotland Under-20s squad ahead of the Junior World Championships in France next month.

Scotland head coach Gregor Townsend said: “There are twin goals for this tour – the first is to build on the work we’ve done so far this season and finish with improved performances. We also have the Rugby World Cup in our thoughts as this will be our last tour before we leave for Japan next year.”

The senior squad has an average age of 25 and contains six uncapped players. With John Barclay rested, Townsend has handed the tour captaincy to hooker Stuart McInally.
