FRANKFURT, Germany (AP) - Arjen Robben scored the opening goal before being taken out on a stretcher with an apparent knee injury Wednesday as title holder Bayern Munich advanced to the German Cup quarterfinals with a 2-0 victory in Augsburg.
Also, Bayer Leverkusen edged Freiburg 2-1, Eintracht Frankfurt defeated second-division Sandhausen 4-2 after a hat trick from Joselu and Wolfsburg needed a late goal from Ivica Olic to prevail 2-1 over another second-tier club, Ingolstadt.
Robben scored in the fourth minute in Augsburg, off a pass from Mario Mandzukic. His first effort was blocked by goalkeeper Marwin Hitz, but he knocked the loose ball into the net.
In the 16th, the match was over for Robben, after a heavy tackle by Hitz. Robben was whistled for offside but Hitz charged into him hard and escaped with a yellow card. Robben was finally taken off the field on a stretcher, bleeding from the right knee. He was taken to a local hospital for treatment.
Thomas Mueller came in for Robben and notched the winner in the 78th with a header after Jerome Boateng's cross following a corner.
''It's the Cup, it's normal for such a game to be a bit hard,'' said Mueller, who had a penalty claim denied.
Bayern labored to the victory although coach Pep Guardiola used his best available lineup. Franck Ribery came in late in the match for his first appearance since cracking a rib Nov. 15 in a match for France.
Leverkusen reached the quarterfinals for the first time in five years by scoring the quickest goal of this season's competition. Robbie Kruse scored 30 seconds into the match by capitalizing on a dreadful error by Freiburg's defense.
The home side pulled level in the 19th through Matthias Ginter, before Emre Can secured Leverkusen's victory in the 77th.
Olic scored in the 89th for Wolfsburg to beat Ingolstadt.
In Frankfurt, the home side got two goals from striker Joselu, one from a 49th-minute penalty. Before Sandhausen struck twice in two minutes to level the score.
Sebastian Rohde scored a clumsy own goal to make the visitors level in the 64th minute. But Vaclav Kadlec and Joselu secured the win for the Frankfurt side, which is winless in nine straight Bundesliga games.
