Bayer Leverkusen says Switzerland striker Eren Derdiyok has been ruled out for several weeks after stepping on a shard of glass.

The Bundesliga club says that Derdiyok needed seven stitches after the accident occurred at his home.

German daily newspaper Bild says the accident happened on Thursday, when Derdiyok stepped on a piece of glass left behind after a toothbrush glass fell and shattered in his bathroom.

The 23-year-old Derdiyok has to rest his left foot for two weeks before he can begin training again.

The injury rules him out of the Champions League tie with Barcelona on Feb. 14.
