Smith told the club's website: "He has a problem at the top of his hamstring and he has had that for a few weeks now. It needed an injection and it means he has to rest for five or six days before he starts training again and hopefully that will settle the problem.
"From our own point of view it is something that had to be done but unfortunately it means he misses the Scotland game. Although he played last Sunday against St Mirren, it is something that has been aggravating him and causing him pain.
"Hopefully the injection will clear that and he will be ready for our game next week against Dundee United."
