Wales manager Chris Coleman suggests the absence of Adam Matthews will be a huge loss for his side's World Cup qualifier with Scotland later this month.
The Celtic full-back injured his hamstring in the Champions League loss to Juventus last week and could miss the Group A qualifier at Hampden on March 22, however, may be back to take on Croatia on the 26th.
"Adam was outstanding against Austria in our last game. He really is developing into a fine young player, so it's disappointing," Coleman said.
"We know he's not available for the first game at least. That's a shame because he plays for Celtic and it would have been a great game for him.
"We don't know about the second game against Croatia yet. There's more time to get him ready for that, so we'll have to see.
"Depending on the grade of the hamstring injury, three or four days extra could make a big difference."
