Scotland back-row Ryan Wilson has been ruled out for the remainder of the Six Nations with a knee ligament injury.
The Glasgow Warriors forward sustained the injury during Scotland's 22-13 defeat at the hands of Ireland at Murrayfield.
The Scottish Rugby Union also confirmed that centre Huw Jones and full-back Stuart Hogg suffered knee and shoulder ligament injuries respectively in the loss at the weekend.
Both players will remain with the squad and they will be assessed by later this week.
Scotland return to Six Nations action on Feb. 23. when they travel to Paris to face France.
