Jordan Archer and Shaun Williams made their international debuts earlier this week.
Archer played in Scotland’s 2-0 defeat to Peru, while Williams’ Republic of Ireland suffered the same fate against France.
Williams, 31, had made his senior debut in Scott Brown’s testimonial last week, however, it was not recorded as an official cap.
Goalkeeper Archer, who kept 18 clean sheets in an impressive Championship campaign with Millwall last season, was at fault for Peru’s goals.
He rushed off his line and diverted the ball into the path of Jefferson Farfan, whose goal-bound shot was blocked by Scott McKenna’s arm for a penalty, which Christian Cueva converted to open the scoring.

Archer would be to blame again when Farfan’s close-range strike squirmed under his arms to double Peru’s lead.
It was a less eventful official debut for Williams, who was an 80th-minute substitute for the Republic of Ireland at the Stade de France.
Both players will hope to impress when Scotland and the Irish take on Mexico and USA, respectively, this weekend.
