Wales captain Sam Warburton may miss this summer's tour to South Africa after dislocating his shoulder in the dying moments of Wales' record breaking 51-3 win against Scotland at the Millennium Stadium.
Head coach Warren Gatland revealed the Wales skipper underwent treatment immediately after the game but faces the prospect of months out of action and may need surgery to correct the problem.
The injury comes as a second blow to a senior player in the space of two weeks after full back Leigh Halfpenny suffered the same injury during last weekend's championship ending defeat to England at Twickenham - an injury which medics have assessed will rule him out of action for around four months.
“I don’t’ think he’s very good", Warren Gatland said.
“It looks like he’s dislocated his shoulder and the had to put it back in after the game so we’ll have him scanned tomorrow but the likelihood is he’ll probably need an operation in that so it looks like that will rule him out for the rest of the season and probably the tour as well."
