Scotland wing Sean Maitland will play no further part in the Six Nations having suffered injuries to his knee and ankle.
The British & Irish Lions star, 25, fell awkwardly during the 28-6 defeat to Ireland in Dublin on Sunday and subsequent scans have revealed significant damage.
Scotland team doctor James Robson told the Scottish Rugby website: "Sean was examined by consultant orthopaedic surgeon Graham Lawson.
"He found that Sean has sustained some damage to the structures of his knee and ankle but, happily, does not require surgery. The expected recovery time for soft tissue damage of this sort is up to eight weeks.
"Sean is now beginning work on his rehabilitation in the care of the Glasgow Warriors medical team."
