Auterac will be hoping to earn full international honours as he is named in the Scotland squad for the first time ahead of their upcoming games against England A, Romania and Georgia.
The 28-year-old – who previously represented England Under-20s – has been named in the 37-man squad that will convene on Tuesday 15 June ahead of their friendly fixture with England A.
Interim Scotland Head Coach, Mike Blair, said: “We have selected a mix of genuine Test match experience and a number of players who have impressed in the recent past to warrant a place in a squad that will want to continue the positive progress we have built up on and off the pitch in recent months.
“With the next Rugby World Cup two years away this period gives us an opportunity to increase our depth in key positions and work with players who can put up their hands for international selection this summer, and beyond.”
Meanwhile, Tuala has been named in the Samoa squad ahead of their summer clashes with Maori All Blacks and Rugby World Cup qualifier against Tonga.
The 31-year-old will be hoping to add to his 22 international caps as the side hope to secure their spot in the 2023 Rugby World Cup.
And incoming Samoa Head Coach Seilala Mapusua said: “This will be my first campaign and considering the impacts of Covid-19, it wasn’t an easy task selecting the Manu.
“However, I am very confident we have the best players to represent the jersey and earn us a spot for Rugby World Cup 2023.”
