Adam Hastings looks set to miss the Six Nations as Scotland continue to be plagued by injury problems in the lead-up to the tournament.
The fly-half damaged his shoulder while playing for Gloucester in their Gallagher Premiership defeat away to Leicester on Christmas Eve.
A statement on the club’s website on Thursday revealed that Hastings will require surgery, while head coach George Skivington said earlier this week “he will not be back any time soon”.
