Wales are not worried about Sam Warburton's fitness despite the captain not being available to face Ireland this weekend.
Head coach Warren Gatland has brought back most of his first choice players for Saturday's game in Dublin, with Warburton a notable absentee.
However the news on Warburton is positive, with Wales taking the cautious approach over their captain's return.
"Warburton has a little knock on his shoulder which is like a pinched nerve," Gatland told reporters.
"It’s nothing serious and he could have played this weekend but we thought we’d give it an extra week."
Gatland also spoke positively about new cap Tomas Francis, who comes in a tighthead prop, while providing an update on Samson Lee.
"We have been really impressed with Tomas since he’s been with us. He’s in good shape but a pretty inexperienced prop at this level. He’s still developing.
"Samson Lee is up and running and did some light scrummaging. He’s not too far away. Tom gets a chance to prove himself this week.
"He’s lost about 7 or 8 kg and conditioning wise he’s just continued to improve. He’s not the only one who has improved but he’ll be in the best shape of his life. He’s got a lot of time to improve and it’s about him enjoying the opportunity on Saturday."
