Scotland skipper Greig Laidlaw has been ruled out of the Dark Blues' autumn Tests after fracturing his ankle, his club side Clermont Auvergne have announced.
The former Edinburgh and Gloucester scrum-half suffered the injury during the French outfit's Champions Cup clash with Ospreys on Sunday.
Although he does not require surgery, Laidlaw has been told he faces 10 to 12 weeks out of action - meaning he will play no part as Gregor Townsend's Scots host Samoa, New Zealand and Australia at BT Murrayfield next month.
He is expected to return to action, however, in time to lead out Scotland for their RBS 6 Nations opener against Wales in Cardiff at the start of February.
It has not been confirmed whether his most recent injury is to the same joint he damaged during this year's Championships.
He tore ankle ligaments in his side's defeat to France in Paris and has not pulled on a dark blue strip since. He missed Scotland's summer Asia-Pacific tour after being called up for duty with the British and Irish Lions on their trip to New Zealand.
