The German international received a knock during Bayern's Wednesday training, and is now confirmed to be out of the Camp Nou battle.

Meanwhile, Bayern Coach Jurgen Klinsmann decided to name substitute keeper Hans-Jorg Butt for the Barcelona clash instead of Michael Rensing.

Rensing produced a woeful performance against Wolfsburg in the Bundesliga on Saturday, where Bayern were thrashed 5-1 by Felix Magath's men.

The Bavarians will be looking to overcome Barcelona and reach their first Champions League final in eight years.
