Scotland winger Nikki Walker faces a race against time to be fit for any of the autumn Tests after breaking a bone in his hand.
The Ospreys star suffered the injury while playing for his club in the first round of the European Cup against Leicester on Sunday.
The bone will take at least three weeks to heal and, with Scotland's first Test against New Zealand on November 8, he is almost certain to watch that match from the sidelines.
There is more of a chance of the former Borders man being fit for the match against South Africa a week later, while he should definitely be in contention to face Canada on November 22.
Simon Danielli of Ulster, Glasgow's Max and Thom Evans, Rory Lamont of Sale, Northampton's Sean Lamont and Edinburgh duo Chris Paterson and Simon Webster were the other wingers named in Frank Hadden's initial squad for the autumn series.
