Wenger also suggested playing for Wales against Andorra could have contributed to the injury and predicted Ramsey would miss the friendly international with Holland on November 13.
The first game Ramsey will miss is the Barclays Premier League clash with Everton on Saturday
Wenger told the Arsenal website: " He had a scan today but he's out
I believe he will be out until after the next international break
"With the (last) international break, the fact that he played against Andorra certainly cost (Gareth) Bale and him as well."
Ramsey and Bale both faced Andorra in a Euro 2016 qualifying match on October 13
Ramsey was taken off injured in the 2-0 Champions League win over Bayern Munich on Tuesday, having played 90 minutes against Watford three days before
