Bayern Munich's fitness issues took another hit on Tuesday, with Thiago Alcantara limping out of the club's 2-1 win over lower-league Rodinghausen.
The win moves Bayern into the DFB-Pokal third round, but was not a performance to inspire much confidence and may have come at a high cost with Thiago's injury.
Corentin Tolisso's knee injury has left the club thin in the middle of the park, with Spain international Thiago having become a crucial piece in the puzzle for manager Nico Kovac.
But Kovac, under pressure with the Bavarian side after a slow start to the season that sees his club sitting second in the Bundesliga after nine matches, may now have to deal without 27-year-old for an extended period, with the Bayern boss admitting that the injury "doesn't look good".
"I hope it is not that bad," Kovac said after the match. "But it doesn't look good."
Bayern have been fighting injury issues throughout the season, with Tolisso, Leon Goretzka, Kingsley Coman, Arjen Robben, Jerome Boateng, Rafinha, Mats Hummels and Franck Ribery among those to have missed time for the club.
The Bundesliga giants now face a nervous wait on Thiago, with the club set to know more on Wednesday following tests on the midfielder.
"He's in a lot of pain right now, but we'll be back in the morning to investigate," the manager concluded.
And while the club have recovered from a poor run of form, winning their last four outings, they face a busy schedule in the coming weeks.
Then comes Der Klassiker, where Bayern face a daunting road trip to take on Bundesliga leaders Borussia Dortmund on November 10.
