Germany international Bastian Schweinsteiger is set to undergo another operation on his right ankle, ruling the Bayern Munich midfield dynamo out indefinitely.
The 29-year old, who underwent surgery on the same ankle in July, needs a further operation after not recovering from the previous as expected, Bayern Munich announced on Friday via their website.
Club doctor Hans-Willhelm Mueller-Wohlfahrt explained ''increasing ossification" was visible in the ankle during recent check-ups, which can lead to tendinitis.
Tendinitis would spell out a very long time on the sidelines for the German, as it's an inflamation of the tendon which links the muscle to bone.
The club said that no improvement's could be made ''despite intensive conservative measures'' and the player's further participation in training and matches ''is no longer possible.''
''The last weeks were again very painful for me,'' Schweinsteiger said. ''I kept trying but am now at a point where surgery is no longer avoidable. I hope to be able to play football completely free of pain again after the operation.''
The German has appeared in each of Bayern's 11 Bundesliga fixtures this season, but is yet to demonstrate the same level of performance which saw him nominated player of the year in Germany last season.
The versatile midfielder is set to miss Germany's upcoming friendlies with Italy and England.
