Injured in April
The 27-year-old German international had appeared as a late substitute in the 2-0 away win against VfL Osnabruck in the previous round but this was his first starting appearance since injuring his right knee in April and he lasted the full 90 minutes.

Stefan Effenberg and Mehmet Scholl also returned to the Bayern team as the German champions recovered from conceding a 13th-minute goal to Wolfsburg's Robson Ponte as Tarnat's fine free-kick levelled the scores on 43 minutes and Elber made it 2-1 a minute later. Bayern will meet 1. FC Kaiserslautern in the last eight.
"The game was enormously important," Effenberg said. "We won, and that was not simple as Wolfsburg played really well, and we are making step-by-step progress." Champions Bayern return to 1. Bundesliga action against FC Schalke 04 on Saturday, and will be eager to improve on the form shown before Christmas that left them in fifth place in the table.
