Scottish Football Association chief executive Gordon Smith wants Kris Boyd to end his self-imposed international exile. The Rangers striker announced last October that he no longer wished to be considered by his country while George Burley remained manager.
"I think he left because he was a bit upset about not being put on the field," Smith said in BBC ALBA's Spors programme.
"I was not too pleased that he walked out and he made it very clear that it was because of the manager and if it was a different manager in charge, he would come back.
"I think that should be sorted out. I'd like to see Kris Boyd change his mind on it, but if he doesn't, we just have to get on with it."
Smith also dismissed suggestions Boyd was not the only player who had a problem with Burley and that some had exaggerated injuries to get out of international duty.
He said: "A lot of people say about people not being available, not turning up for matches, injuries.
"Our medical staff check everybody out and they know, when somebody's allowed to leave the squad, they're genuine cases of injury.
"No-one is allowed to leave the squad on the basis of made-up injuries."
