North set for spell on sidelines
Scarlets wing George North will be out for three months after undergoing shoulder surgery.
The 18-year-old, who scored two tries on his Wales debut against South Africa, picked up the injury on international duty.
Scarlets head coach Nigel Davies said: "Our policy with any soft tissue injury is to get a scan done immediately to ascertain the extent of the injury. The scan revealed in this case that George required surgery to ensure there was no further damage."
Davies added: "Potentially if not repaired, he could have suffered a dislocated shoulder which would have been a lot worse for such a young player at the very start of his career.
"In today's physically demanding game, it is crucial that the best interests of our players' long-term playing career are supported fully.
"It is obviously disappointing and frustrating for George and it's a blow to his colleagues at the Scarlets as he's had such a great start to his career in the senior team.
"But this is the right decision for him as a player and ultimately for the Scarlets in terms of getting him back fully fit and well and helping him develop further as a player with a very bright rugby career."
It is a further blow for Scarlets, who are missing props Peter Edwards and Deacon Manu for up to 12 weeks with fractured forearms and Rhys Thomas currently recovering from a fractured leg.
As a result, Scarlets have registered 20-year-old tight-head prop Simon Gardiner in their European squad.
