Gary Caldwell will lead Scotland out for the first time in Wednesday's friendly against Slovenia.
The Wigan defender has been named captain in the absence of Darren Fletcher after manager Craig Levein decided to rest Kenny Miller from the start. Celtic's Charlie Mulgrew will win his first cap while Bristol City's Richard Foster was added to the squad after Alan Hutton became the fourth player to pull out.
Caldwell will win his 47th cap in the international in Koper. He said: "I've never started the game as captain. Obviously Fletch is the captain and Kenny is the vice-captain so it is an honour to get it, but they are obviously the men in possession and I am 100% behind them."
He added: "But to get it for one night will be special."
Levein revealed the versatile Mulgrew would play at full-back.
"Charlie will play left-back," Levein said at Glasgow Airport. "He would have been in the squad in November in Cyprus but he was injured. He was gutted that he couldn't make it.
"He is playing out his skin, he has improved enormously."
Miller will not start after Cardiff manager Malky Mackay asked Levein to use the 32-year-old sparingly following their Carling Cup final shootout defeat by Liverpool.
"Kenny will be on the bench but the manager has named a team that will be very, very competitive from the first whistle," coach Kenny Black said. "There will be an opportunity for lads to maybe get part of the game.
"Kenny is desperate to play but you saw the game on Sunday, the cup final, and we just felt it would be better having Kenny as back-up. Craig Mackail-Smith will play up front."
