Three Scots are set to make their international rugby debuts against Samoa this weekend.

Edinburgh Rugby full-back Greig Tonks, 24, and Glasgow Warriors duo Alex Dunbar, 23, and Pat MacArthur, 26, have been named in the squad that will take on Samoa in Durban on Saturday, June 8.

Uncapped players Stevie Lawrie, Peter Horne and Duncan Taylor will be on the bench for the game.

Bath Rugby's Tom Heathcote and Edinburgh Rugby's Grant Gilchrist, who have one Scotland cap each, have also been named in the squad.

In all, there are five player changes and one positional switch from Scotland's last game, which ended in a narrow defeat to France in the RBS 6 Nations Championships in March.

Scotland head coach Scott Johnson said: "We want to broaden the base and it (selection) gives us the perfect opportunity to see how these guys stand up in Test footy."

Johnson ranked Scotland's win in Samoa last year as a tremendous achievement and expects a fierce encounter this weekend.

He said: "They have all the artillery coming for our game and we're going out to compete on all fronts. We have 25 Test matches available to us prior to the World Cup. I've said regularly that we're not going to give Test jerseys away but we cannot be exposed to injury issues (come RWC) and the best way to prevent that is to give players opportunities."

Scotland will play Samoa in the Castle Lager Test Series at King's Park, Durban on Saturday, June 8. Kick-off is at 2.15pm local time (1.15pm BST).
