St Johnstone goalkeeper Alan Mannus has been ruled out of action for six weeks with a shoulder injury.
The 31-year-old, who had been due to turn out for Northern Ireland against Russia this evening, suffered the injury in the latter stages of Sunday's 0-0 draw with Kilmarnock.
"Scans have revealed damage which means the lengthy period of rest including an initial 10 days in a sling," read a statement on the club's official website.
Stevie Banks, 42, is expected to replace the stopper between the sticks.
