Neil Cochrane has replaced the injured George Turner in the Scotland squad for their Six Nations training camp.
Turner suffered a knee injury as Glasgow Warriors beat Exeter Chiefs at the weekend, opening the door for Edinburgh Rugby hooker Cochrane to come into Gregor Townsend's group.
Lock Richie Gray, who had returned to the Scotland fold, will also be absent for the three-day camp due to a calf issue.
Townsend had originally named a 40-man selection, including former captain Greig Laidlaw.
