Rovers and Scotland skipper Charlie Mulgrew said captaining his country was "a proud moment" for him, despite defeat to Costa Rica at Hampden Park.
Marco Urena's first half goal proved the difference in Alex McLeish's first game since returning as national team manager.
A pair of ex-Rovers in Grant Hanley and Tom Cairney were also included in the starting XI, and despite losing the game, Charlie said wearing the armband for his country was a special occasion for him.
"It was a proud moment, all my family were here. I'm honoured," he told reporters after the game.
"In the first half we didn't press as a team and didn't sit off as a team, and that's where we got most of our problems. We sorted that at half-time and [there were] definitely encouraging signs.
"The message was nice and clear at half time: get up higher, get pressing. You saw that in the second half, they never had much and we dominated.
"Oli [McBurnie] put himself about and it was a difficult shift for him up there. He didn't see much of the ball but when he did he held it in well and did ok. We're delighted to have all these players and we will get stronger as we go forward.
"You always want to win the game and we're disappointed we didn't, but we need to take the positives, move on quickly and be ready when the competitive games come around."
Mulgrew and Scotland are next in action on Tuesday when McLeish takes his side to the Groupama Arena in Budapest to take on Hungary.
