Scotland centre Alex Dunbar limped off early in the second half of Glasgow Warriors’ 22-5 win over Racing 92 in the European Rugby Champions Cup yesterday, sparking fears for his availability for the Six Nations.
Dunbar, who missed the World Cup through injury, appears to have aggravated a problem which caused him trouble earlier in the season.
Glasgow coach Gregor Townsend said: “He missed three weeks with a groin/hamstring strain and he felt something twinge there. It was the same hamstring. He was over the ball and he felt it tighten. He doesn’t think it is as bad as the last time.”
Scotland kick off their Six Nations campaign at home to England on 6 February.
