Arsenal‘s Mesut Ozil has been ruled out for up to 12 weeks with a knee injury.

The 25-year-old ex-Real Madrid midfielder, who is currently on international duty with Germany, played 90 minutes in Arsenal’s 2-0 defeat at Stamford Bridge last weekend. He left to join the Germany camp but with a problem in his left knee. An MRI was held earlier today which showed damage to the joint. He has subsequently been ruled out for three months with the injury. Ozil will only be able to join his Arsenal teammates after Chritsmas, and most probably in the starting of the new year of 2015.

A statement on the German Football Association website read:

The statement read: “The Arsenal playmaker already complained about pains in his left knee when arriving at Frankfurt.

“A MRI scan at team doctor Dr. Hans-Wilhelm Muller-Wohlfahrt today revealed a partial lateral collateral ligament tear in left knee. The treatment will be non-operative with a six-week immobilisation of the knee. Mesut Ozil is likely to be out for 10 to 12 weeks.”

Ozil will miss Germany’s Euro 2016 qualifiers against Poland on Saturday and the Republic of Ireland next Tuesday. He is also almost certainly out of the national team’s fixtures against Gibraltar and Spain in November.

Ozil apparently first felt the injury during the game against Chelsea but was keen on playing through the pain. He reported the problem to Arsenal’s medical staff later and they subsequently instructed Germany’s doctors to look at properly after he joint his international teammates.

The 25 year old is now expected to return to London for Arsenal’s medical staff to make their own assessment.

The attacking midfielder signed from Real Madrid for a club record £42.4m in September 2013 and has scored eight goals in 46 starts. He has been criticized for his recent form but the German would surely be a huge miss for the Gunners. Arsene Wenger is without Aaron Ramsey, Mikel Arteta, Serge Gnabry, Mathieu Debuchy, Olivier Giroud, Yaya Sanogo and Theo Walcott at the moment as all the aforementioned players are out on the sidelines with injury.
