Scotland have been hit with a fresh injury blow after lock Richie Gray was told his RBS 6 Nations Championship is over.

The Castres forward suffered an upper arm injury during Sunday's 26-23 defeat to Wales at Murrayfield and scans now show it will be 12 weeks before he can resume playing duties.

The news that he will miss the remaining fixtures with Italy, England and Ireland comes just a day after prop Jon Welsh - who scored a late try against the Dragons - has also been ruled out of the remainder of the competition with a fractured hand.
