Scotland head coach Vern Cotter has added two players to the Scotland squad ahead of this Saturday's Calcutta Cup match against England at Twickenham.
British and Irish Lions full-back/wing Sean Maitland, who continues his recovery from a shoulder injury sustained in January, has taken the place of Glasgow Warriors club mate, Sean Lamont, who has been ruled out of the rest of the Championship with a knee injury suffered in the Warriors' bonus-point win over Zebre on Friday.
Lamont has returned to the care of his club's medical team for further assessment and treatment.
Edinburgh hooker, Stuart McInally, has also been drafted into the squad as precautionary cover for Ross Ford, who continues his recuperation from the back spasm suffered against Italy in the Six Nations.
McInally, 24, a Scotland captain at every age-grade, was an unused back-row replacement against South Africa in the autumn of 2012, but began a switch from number eight to the front-row in August 2013 after 58 appearances for his club.
The Scotland medical team also confirmed that Glasgow Warriors back Peter Horne suffered a concussion in his club's match against Zebre and is expected to begin his graduated return to play protocol this morning.
