Bayern Munich midfielder Franck Ribery is facing another spell out of action after it was confirmed that he suffered a serious knee injury in the 2-2 draw with Hertha Berlin.
The 34-year-old overextended his left leg during the second half of a match that saw the defending champions throw away another two-goal lead.
France international Ribery has torn the lateral cruciate ligament in his left knee, likely ruling him out until the tail end of the season and making him a fitness doubt for the World Cup.
Bayern CEO Karl-Heinz Rummenigge told the club's official website: "We're sorry Franck has hurt himself. We all wish him a quick and good improvement."
Ribery had made nine appearances for Bayern prior to sustaining the injury, scoring one goal during that time.
