"Sacha Boey will be out of action for Bayern for several weeks after the right-back suffered a meniscus tear in his left knee in training on Sunday, as confirmed following examination by the club's medical department," Bayern Munich said in a statement.
"The 24-year-old has already undergone a successful operation," the club added.
