Following an injury update, Liam Williams is set to miss the games against Ireland and France this month.
The 28-year-old has not played a game since sustaining the blow during the World Cup in Japan and has already missed the opening game of the Six Nations tournament against Italy.
“Liam’s struggling a bit at the moment,” said Wales defence coach Byron Hayward.
“It [Saturday’s game] is a little bit early for Liam. We are possibly looking at the fourth or fifth games in the championship.
“Leigh Halfpenny had a great game last weekend at fullback, though it would be nice to get Liam back.”
According to Hayward’s timescale, Williams could be considered for the match against England on March 7 and the final game against Scotland the following week.
Wales are scheduled to name their team to face Ireland on Thursday, 6 February at 11am.
