Adam Ashe will become the seventh player to make his Scotland debut this summer after being named in the XV to face South Africa in Port Elizabeth tomorrow.

Glasgow Wa rriors No.8 Ashe has only played 36 minutes of professional rugby this season due to injury, but is one of four changes to the Scotland starting line-up that won in Argentina.

The 20-year-old Ashe has joined the squad from New Zealand where he was training at Canterbury University in Christchurch after winning the John McPhail scholarship, a programme meant to identify and develop exciting young prospects for the future.

Scotland coach Vern Cotter has no doubts the youngster is ready, saying: "He has been identified as a talent, that is why he was on that scholarship.

"He has been plying his trade in Canterbury and I think they are pretty good judges of quality and character down there and he has come back with positive feedback on what he has been doing."

Though Scotland arrive in Port Elizabeth unbeaten on this tour, Cotter is under no illusion this is by far their sternest test, even though the Springboks have also been forced into a raft of changes.

"They are very strong," he said. "Very strong from driven line-outs, they will be physical but we can't just expect them to try to dominate us. They will move the ball at certain times as well.
