Borussia Dortmund defender Neven Subotic has been ruled out for up to six months after tearing two anterior cruciate ligaments in his knee.

The 24-year-old was stretchered off shortly before half time in this afternoon's 2-1 defeat at Wolfsburg after landing awkwardly following a challenge from Ivica Olic.

"Sadly I did not get good news regarding my injury. 2 of my ACL's are torn. But no worries, I will be back stronger," he posted on his Facebook page.

The Serbian international has started 13 games in all competitions this season.
