Wales have been hit by a blow after Scott Williams was ruled out of the rest of the Six Nations due to injury.
The 23-year-old Scarlet suffered the shoulder injury in last Saturday's clash with Ireland in Dublin, when making a hit on Brian O'Driscoll.
Williams is set to have surgery on Thursday and is expected to be sidelined for three months, which means his season is prematurely ended.
"He took a major blow to his A/C joint and is under review at the moment," Scarlets head coach Simon Easterby revealed to walesonline.co.uk.
"He is clearly not going to be playing for a number of weeks and won't take any more part in the Six Nations.
"It's a big blow because he has been playing well and we are delighted he has committed his future to us.
"But unfortunately these things happen and he will deal with it."
