The winger, who has been in the form of his career, injured his knee in the first half of Edinburgh’s home loss to Munster on Friday night. After receiving the results of a scan his club expect him to be out until February, although the exact timing of his return will depend on how he responds to rehab.
Scotland open their Six Nations campaign with the Calcutta Cup clash against England at Twickenham on February 4, before hosting Wales at Murrayfield a week later. There is then a gap of a fortnight before Gregor Townsend’s side travel to Paris to face France in the third round on February 26. The Scots’ final two games are both at home, against Ireland on March 12 and Italy on March 18.
Graham is the top try-scorer in the United Rugby Championship this season with nine, and also excelled for the national side in the recent autumn Tests, scoring one try against New Zealand and a hat-trick against Argentina. The 25-year-old damaged his medial collateral ligament - the inner side of his knee joint - against Munster after falling awkwardly.
A statement from Edinburgh said: “Darcy Graham will miss the upcoming festive fixtures through injury with the Scotland international winger expected to be sidelined until February. Graham picked up a knee (MCL) injury in last weekend’s BKT United Rugby Championship contest against Munster at DAM Health Stadium and left the match in the 26th minute. Graham will remain under the care of the Edinburgh Rugby medical team during his rehab period.”
The 25-year-old’s injury means he will also miss all four of Edinburgh pool stage matches in the Heineken Champions Cup as well as the festive 1872 Cup double-header with Glasgow Warriors.
Graham’s tries in the recent autumn series took his Test tally to 16 in 33 matches and drew praise from Townsend. Asked if Graham was currently the best winger in the northern hemisphere, the national coach said: “He must be up there. He’s such a threat. Yes, he’s a finisher but also a creator. Everyone loves him in our squad because he trains at that level and he’s so tough.”
