Calf problem sidelines Ramsey
Aaron Ramsey is a major doubt for Arsenal's Premier League visit to Sunderland on Saturday because of a calf problem.
The 22-year-old was forced to withdraw from the Wales squad for Wednesday's friendly against Austria at the Liberty Stadium.
Ramsey has returned to Arsenal for treatment and could miss this weekend's trip to the Stadium of Light.
A Football Association of Wales statement on Wednesday read: "Aaron Ramsey has this afternoon withdrawn from the Wales squad to face Austria at the Liberty Stadium in Swansea.
"Aaron has a problem with his calf and has returned to his club Arsenal for treatment."
Midfielder Ramsey has made 32 appearances for the Gunners this season, scoring once.
