Musiala was subsequently able to rise to his feet after a medical examination and a thumbs up from the medical staff. Speaking after the game, Bayern board member Max Eberl helped ease concerns on the midfielder.
“He’s doing well, that’s the most important thing,” Eberl told Bild, providing a brief update.
Bayern goalkeeper Manuel Neuer said: "It will become clear what it was. But of course we are keeping our fingers crossed."
Musiala is expected to rest and recover over the next few days ahead of the clash against Borussia Dortmund in the DFL Super Cup next weekend.
