Arsenal midfielder Aaron Ramsey will be sidelined for at least three weeks after sustaining a calf injury during Tuesday’s European Champions League tie against Bayern Munich.

The 24-year-old had to leave the field during his team’s 2-0 victory over Bayern at the Emirates Stadium in the third round of the Champions League, Efe reported.

Arsenal confirmed on Thursday on its official website that the Welshman underwent a MRI scan and would be out for about three weeks.

"He’s had a scan today but he’s out. "I believe he will be out until after the next international break," Arsenal head coach Arsene Wenger stated.

"With the (last) international break, the fact that he played against Andorra certainly cost (Gareth) Bale and him as well," the coach added.
