Bayern Munich have confirmed Niklas Sule tore the anterior cruciate ligament in his left knee during the Bundesliga draw against Augsburg.
Germany centre-back Sule will undergo surgery on Sunday after scans confirmed head coach Niko Kovac's fears of a serious injury.
Sule, 24, went down clutching his left leg after going into a challenge with Florian Niederlechner in the early stages of the 2-2 draw in Bavaria.
