Scotland head coach Vern Cotter has paired brothers Richie and Jonny Gray together in the second row in his side to face Argentina at BT Murrayfield on Saturday.
It is a second start and sixth cap overall for 20-year-old Jonny, while his 25-year-old older sibling – a British & Irish Lion – will win his 40th cap.
Gray is not the only promising young player to earn the right to start the nation’s opening autumn Test, with 21-year-old Glasgow Warrior Mark Bennett set to win his first cap at outside-centre.
Only two Edinburgh players have been selected to start, with Alasdair Dickinson and Ross Ford lining up in the front row.
Cotter said: “We’ve been studying these players since the start of the season and have selected a group we believe can do the job in this Saturday’s Test match against Argentina.
“We have several performance-related themes, and have looked for people who have the ability to control games, take initiative, can pick up the ball and run with it, who like physical confrontation and can keep the ball alive.
“These are things that we have prioritised in our selection and we’re now all looking forward to getting out there and putting in a good performance in front of the Scottish people on Saturday.”
