Allister Hogg's knee injury is not as bad as first feared and the Scotland forward could still play a part in the RBS 6 Nations.
The Edinburgh back rower, who injured his left knee in his club's European Cup win over Perpignan on Sunday, underwent a scan on Tuesday morning.
And, although Hogg will miss the RBS 6 Nations opener against France in Paris and the visit of Ireland on February 12, he could be available for the Murrayfield clash with Italy on February 26.
Scotland team doctor James Robson said: "The scan revealed moderate damage to knee ligaments.
"The estimated recovery time is three to four weeks - considerably better than was first feared on his initial assessment.''
The prognosis will be small relief for Scotland coach Matt Williams, who is already resigned to being without openside flanker Donnie Macfadyen for the start of the tournament.
British and Irish Lion Simon Taylor is still to return to action after the knee injury he sustained in the final match of last year's championship, while 24 players were unable to train at Murrayfield because they were suffering from bumps and bruises from the weekend's matches.
