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.
