Adam Ashe will make his Test debut on Saturday when he starts at No.8 for Scotland against South Africa in Port Elizabeth.
The 20-year-old Glasgow Warrior is one of four changes to the team that narrowly beat Argentina 21-19 in Cordoba last weekend as he takes over from London Irish Kieran Low at the back of the scrum.
The other changes see Henry Pyrgos start instead of Grayson Hart at scrum-half while Tim Swinson is preferred to Jonny Gray at lock.
Finally Chris Fusaro is promoted from the bench in place of Blair Cowan who has returned home.
“Adam is a talented player and the reports of his form in New Zealand have been very positive,” said head coach Verb Cotter.
“He's trained well with us and looked sharp. He is a specialist No 8 and this is a golden opportunity for him.
“I've always regarded playing South Africa in South Africa as the benchmark. It's a massive challenge and it gives our boys an opportunity to lift their level.
“If we can make accurate choices in the way we play and impose our form of rugby then I think that will be a shift in the right direction.
“I've been pleased with the initiative that's developing within the team. We're starting to get good variety in our game. Now it's a matter of seeing if we can do it against very good opposition.
