Scotland's injury-ravaged back-row forward Jason White will miss the Six Nations after breaking his leg.
White suffered the injury during a training session with his French club Clermont Auvergne on Friday.
White, a former captain and known as one of the hardest tacklers in the game, had surgery on Saturday.
He is expected to be out of action for around three months.
Scotland begin their Six Nations campaign against France at Murrayfield on February 7.
