Aaron Ramsey injury worry as Jonny Williams misses Wales qualifiers
Aaron Ramsey is an injury worry for Wales' opening World Cup qualifier against Moldova on 5 September.
Midfielder Ramsey, 25, came off in Arsenal's Premier League opener against Liverpool because of hamstring damage.
An Arsenal spokesman confirmed: "Aaron has a hamstring injury and is being assessed."
The injury came after news that Crystal Palace midfielder Jonny Williams, 22, will miss Wales' opening three qualifiers with an ankle injury.
Williams was injured in a pre-season friendly against non-league Farnborough and is expected to be out for up to 10 weeks, making him a doubt for the games against Austria and Georgia in October.
He was part of the Wales squad for Euro 2016, starting the opening game against Slovakia.
"It's another injury for Jonny and we hope it's not too long," Wales assistant manager Osian Roberts told BBC Radio Wales Sport.
"It's really disappointing for Jonny because we thought this would be the season he would make that major step in his career.
"It's really disappointing it's come in a friendly and I've seen the tackle, it's a poor one and one we don't want to see in the game anymore.
"It's one from behind with both legs wrapped around the ankle and subsequently it's another injury for Jonny."
