Craig Levein has praised Barry Robson’s commitment to the national team, hailing him as an example to every member of his squad.
Earlier this week the midfielder expressed his desire to make the 9,000 mile trip from Vancouver to play for his country.
The 33-year-old signed for MLS side Vancouver Whitecaps from Middlesbrough and misses the friendly against the USA to earn his coaching badges.
After calling time on Steven Fletcher’s international career earlier this month after the striker declared himself unavailable for a match back in 2011.
And Levein says Robson’s willingness to make sacrifices to represent the national team should be replicated across the squad.
He said: "He [Robson] is a great lad. He is an experienced player who just loves playing for his country.
"I value that, I value people who would do anything to play for their country.
"It sounds simple, you think everybody would, but I've had experiences where that's not the case.
"This attitude that everybody wants to be here is really important to me."
Shaun Maloney and Andy Webster were handed starting spots for the match in Florida while Craig Bryson earned a recall to the squad after a fine debut season with Derby County.
And the former Dundee United boss wants other fringe men like Chris Burke, Kris Boyd and James McFadden to retain hope they can force their way into his plans.
He added: "The door is not closed.
"McFadden has hardly played any football and Boydy has been flitting about here, there and everywhere.
"Chris Burke is one who is on the radar, I had a chat with Chris at the end of the season. The group is getting strengthened all the time."
