Wales skipper Sam Warburton is likely to miss "several months" of action after dislocating his shoulder against Scotland, his club side Cardiff Blues have announced.
The flanker suffered the injury in the closing stages of Saturday's clash as Warren Gatland's side ran up a record-breaking 51-3 win at the Millennium Stadium in their final RBS 6 Nations clash of the campaign.
Warburton will now miss the rest of the RaboDirect Pro12 season and Wales' summer tour to South Africa after it was confirmed he would undergo surgery this week.
The British and Irish Lions forward joins Wales team-mate Leigh Halfpenny on the sidelines, after the full-back had successful surgery on his shoulder last week.
A statement on the Blues website said: "Following MRI scans and consultations with specialists, Warburton will have an operation and is expected to miss several months of action.
"Everybody at Cardiff Blues wishes Sam and Leigh all the best during their rehabilitation."
