The Champions League hopes of Bayern Munich were severely compromised with injuries sustained on Tuesday to Robert Lewandowski and Arjen Robben.

Lewandowski suffered a broken jaw and nose, while Robben has been ruled out for the remainder of the season with a torn calf muscle.

Lewandowski was injured in a collision with Dortmund goalkeeper Mitch Langerak with four minutes of extra time remaining.

Lewandowski was sent to hospital for a CT scan after the match, and on Wednesday morning the club announced his injuries but stopped short of ruling him out for the rest of the campaign.

Bayern plays Barcelona next week in the Champions League.
