Williams ruled out of Six Nations

RUGBY UNION: Wales centre Scott Williams is to undergo a shoulder operation today and will miss the rest of the Six Nations. The 23-year-old suffered the injury during the first half of last weekend’s 26-4 defeat by Ireland. Coach Warren Gatland fears he will also be without centre Jonathan Davies against France next weekend following a chest injury. Gatland said: “He has been rescanned. He is still not 100 per cent.”
