Bayern Munich's Robert Lewandowski ruled out for four weeks with knee injury

Bayern Munich striker Robert Lewandowski faces four weeks on the sidelines after sustaining a knee injury in his side's UEFA Champions League win over Chelsea on Tuesday.

The 31-year-old played the full 90 minutes at Stamford Bridge, and scored his side's third goal to seal a 3-0 victory and put Hansi Flick's men in the driving seat of their last-16 tie.

However, a club statement on Wednesday revealed that Lewandowski had undergone a comprehensive examination by the medical staff, headed by Dr. Hans-Wilhelm Müller-Wohlfahrt, upon the team's return to Munich, where the injury to his left knee was confirmed.

Lewandowski's knee will be immobilised in a cast for 10 days before he can began rehabilitation training.

The expected four-week timeline for his return means that the Polish hitman is likely to miss Bayern's next four Bundesliga fixtures, starting with the trip to Hoffenheim this weekend, as well as matches against Augsburg, Union Berlin and Eintracht Frankfurt.

He will also play no part in the DFB Cup quarter-final against Schalke on 3 March or the Champions League return meeting with Chelsea at the Allianz Arena on 18 March, but could make his comeback in Der Klassiker with Borussia Dortmund on Matchday 28.
