Augsburg held on to stun the Bundesliga leader with a 2-1 win in their Bavarian derby on Friday to climb out of the relegation zone.
It was only Augsburg’s third win in 21 league games against its powerful southeastern neighbor, which fell to its second defeat of the season.
Bayern had won 16 of their previous 20 meetings.
It was clear that Bayern missed Joshua Kimmich’s presence in midfield.
The unvaccinated 26-year-old is in quarantine for the second time in as many weeks after coming into contact with someone with COVID-19.
Bayern was also without Niklas Sule and Josip Stanisic, who tested positive for COVID-19. Augsburg was without winger Ruben Vargas for the same reason.
