Scarlets wing Morgan Stoddart will miss Wales' pre-World Cup training camp in Poland next week after suffering a thigh strain.
Stoddart picked up the injury during training and will remain in Wales for treatment.
The Wales squad leave for the first of two separate week-long training camps in Spala in Poland on Saturday.
However Stoddart is expected to be available for the second camp, which takes place the week beginning 18 July.
"Morgan has picked up a strain to the quad muscle in his thigh and will need to be managed over the next couple of weeks," said WRU national medical performance manager Prav Mathema.
"Although the injury is mild, Spala will be an intense training camp and Morgan will not get the maximum benefit out of it with the injury he is carrying.
"We have consulted closely with the Scarlets medical team and concluded the best thing for him is to miss this first trip and get himself right in time for the second one."
Stoddart has won seven caps for Wales and scored a try on his debut against World Champions South Africa in 2007.
