Former Selkirk centre Alex Dunbar has been included in the Scotland squad for this first time.
The Glasgow Warrior will travel as part of the national team which heads to South Africa to play against the Springboks and Samoa in a four-team tournament which also involves Italy.
The only other Borderers involved are Greig Laidlaw, Kelly Brown, Geoff Cross and Ross Ford, with Hawick’s Stuart Hogg picked for the British Lions last week.
Scotland head coach Scott Johnson said: “First up, it’s a strong squad designed to win test matches against quality opposition.
“We’ve continued to monitor the players’ form closely and we’ve been pleased that Glasgow have reached the knockout stages of the Rabo.
“We are taking the opportunity to have a look at some players and want to assess what they’re like at this level. We need to be able to find out whether players who’ve done the business for their clubs can replicate that form in international footy.
“We also want to enable certain players who are known to us – for example Nick De Luca and Max Evans – to have the sort of off-season physical preparation that they’ve not had for a few years because of the demands of touring schedules.”
Saturday, June 8 v Samoa, King’s Park, Durban; Saturday, June 15 v South Africa, Mbombela Stadium, Nelspruit; Saturday, June 22 match to determine final placings, Loftus Versfeld, Pretoria.
