Six Nations 2014: Scott Williams injury worry for Wales

Wales centre Scott Williams is still having his shoulder injury assessed ahead of their Six Nations clash against France on 21 February.

He left the field after damaging a shoulder in a first-half tackle on opposite number Brian O'Driscoll in Wales' 26-3 defeat by Ireland.

Scarlets star Williams is being medically assessed this week.

Wales began their title defence against Italy without centre Jonathan Davies, who had a pectoral injury.

British and Irish Lion Davies returned in the LV= Cup defeat at London Irish on 1 February.

He sat out the Pro12 win on Saturday at Treviso, but could face Ulster in that competition seven days before Wales host France at the Millennium Stadium.
