Bayer Leverkusen midfielder Gonzalo Castro will miss the rest of the current campaign after picking up a knee injury in training.
The 27-year-old suffered a meniscus tear on Wednesday morning and requires surgery, preventing him from playing any part in Bayer's push for Champions League qualification.
A statement on the club's official website said: "Bayer go into the final sprint of the season without their midfield ace Gonzalo Castro.
"Bayer's all-rounder retired during training on Wednesday morning with a tear of the medial meniscus in his left knee."
Castro, a graduate of the club's academy, has scored two goals in 20 league appearances this term.
