Philipp Lahm will be out of action for three months after suffering a fractured ankle in training on Tuesday with Bayern Munich.
The club tweeted: "Big blow for Philipp Lahm: The captain has suffered a fractured ankle. He needs an operation and will be out for around three months!"
The player had to be stretchered off on a golf cart following the training accident, which the club said did not involve another player.
