London - Scotland's Six Nations campaign was hit by a fresh blow on Tuesday with the news that lock Richie Gray will miss the rest of the tournament with an arm injury.
The 25-year-old Castres forward, elder brother of international colleague Jonny Gray, damaged a tendon in his upper arm during Scotland's 26-23 loss to Wales on Sunday and will be sidelined for "three to four months".
"Richie Gray has been ruled out of the remainder of the RBS 6 Nations Championship with an arm injury," Scottish Rugby announced on Twitter.
