Edinburgh Rugby lock Grant Gilchrist could make his Test debut for Scotland in Saturday's EMC Test against Tonga in Aberdeen.
The 22-year-old, a recipient of the 2011 John MacPhail Scholarship, has been selected for a Scotland match-day 23 for the first time along with the uncapped 20-year-old Bath Rugby outside half Tom Heathcote.
Gilchrist could get his international chance off the replacements bench just a year after making his Heineken Cup debut against London Irish, the 6'7" second row appearing in seven of the club's matches in their run to last season's semi-finals when Edinburgh became the first Scottish club to qualify for the last four.
And Scotland have made five changes in personnel from the team that started against South Africa for the Tongan test.
Head coach Andy Robinson has also made four changes on the bench as Scotland seek to protect their 100% winning record at their northern citadel in front of an expected capacity crowd.
The changes in the team see Max Evans return at outside centre to the stadium where he won his first cap four years ago. He replaces Nick De Luca who is on the bench.
Henry Pyrgos, who scored Scotland's try against South Africa last weekend, is handed the starting jersey at scrum-half for the first time instead of Mike Blair, while Scott Lawson will begin his first international since August 2011 at hooker rather than Ross Ford.
At lock, Alastair Kellock gets the nod over Jim Hamilton to win his 47th cap, while in the back-row Alasdair Strokosch is restored from the calf injury that prevented his involvement against the Springboks.
Robinson said: "We will not be among the top eight seeds for the 2015 Rugby World Cup draw, so this weekend I'm looking at giving a number of players an opportunity to put their hand up for selection for next year.
"This weekend we have to put together an 80 minutes performance and build on the positive parts of our games that we showed in the last 30 minutes against South Africa and the second half against New Zealand.
"International rugby is about pressure and it's important that you convert your pressure into points and when you are under pressure that you are able to absorb it as opposed to conceding points as cheaply as we have done."
