Birmingham City defender Paul Caddis drafted into Scotland squad
The former Celtic defender flew out with Gordon Strachan's side to Serbia on Monday.
Paul Caddis has been called in to the Scotland squad for the World Cup qualifier with Serbia.
The Birmingham City defender flew out with the team from Glasgow Airport on Monday morning, providing cover for the injured Russell Martin.
Formerly of Celtic, the 24-year-old has been at St Andrews since the start of the season, having joined on loan from Swindon Town.
"We are really short on bodies and we had to decide who we can bring in, who I knew I could trust and I seen him play recently," Scotland boss Gordon Strachan said of the call-up.
"He has pace, ability to beat people and is a good defender, the only thing is, like myself, he is quite short.
"I'm sure if he was six foot he would be a real top, top player but he has dealt with that and put himself into a position where I pick him.
"There are a lot of people in the treatment room, which is fair play to them, they have come across and wanted to give it a shot."
Caddis, who won League Two with the Robins last season, has played 20 times for Championship side Birmingham this campaign.
Capped 13 times at Under-21 level by Scotland, the right back made 24 appearances for Celtic and also spent time on loan at Dundee United, playing on 11 occasions.
A move to Swindon followed in 2010, where he played 91 times, before moving on to Birmingham City.
