Josip Stanisic will miss the start of Bayern Munich's Bundesliga campaign after undergoing knee surgery.

The defender, who has returned to the club after a successful loan spell with Bundesliga champions Bayer Leverkusen, tore a collateral ligament in his right knee during training on Monday.

Stanisic, who started Bayern's 4-0 victory over Ulm in the DFB-Pokal last Friday, is set to be out for several weeks, according to a statement released by the club.

The Croatia international won the league and DFB-Pokal last season, making 20 appearances in the Bundesliga for Leverkusen during their unbeaten domestic run.

Vincent Kompany's men will kick off their top-flight campaign against Wolfsburg on Sunday.
