Scotland full-back Hugo Southwell will miss the World Cup after failing to recover in time from a knee problem.
The 31-year-old Stade Francais man suffered the injury in May and missed the French side's Amlin Challenge Cup final defeat by Harlequins.
"After talking this through with Hugo we've decided to stand him down from our World Cup squad by mutual consent," said head coach Andy Robinson.
Scotland begin their World Cup campaign against Romania on 10 September.
Prior to the tournament in New Zealand, Robinson's men host Ireland on Saturday, 6 August and then entertain Italy two weeks later.
"Hugo has been working hard to recover from a knee injury but has not been able to take a full part in our training camp," added Robinson.
"While he may be fit to resume playing in mid-late August both Hugo and I have decided that he will not be part of our World Cup plans.
"Hugo has been very diligent in his rehabilitation programme and I'm sure he will be determined to perform for Scotland again in the future."
Capped 59 times, Southwell played in this year's Six Nations defeats by France and Wales.
He lost his starting place to Chris Paterson after sustaining a facial injury, following a reckless tackle on Wales' Lee Byrne at Murrayfield.
