Uncapped winger Simon Webster has been added to the Scotland squad for Saturday's Six Nations match against Italy at Murrayfield following an injury to centre James McLaren.
McLaren took a knock on his collar bone in Saturday's 40-9 loss to England at Twickenham and his condition is being assessed by the Scotland medical team.
Webster (22) - capped eight times at under-21 level - played in the winning Scotland A side against Fiji last November.
