But the 58-times capped Scotland scrum-half - who kicked the winning points against Ireland in round one of this year's Championship - limped off in the first half in the Stade de France on Sunday afternoon.
And the 31-year-old - who is likely to be replaced by Ali Price in the starting XV to take on Wales in round three - is now out of contention for the rest of the campaign.
