Austrian media have accused Germany coach Julian Nagelsmann of telling goalkeeper Kevin Trapp to feign injury during their clash on Tuesday night.
The two nations faced off in a friendly in Vienna, with the hosts winning 2-0 thanks to goals from Marcel Sabitzer and Christoph Baumgartner.
Leroy Sane also saw red for the Germans for pushing Philipp Mwene as things went from bad to worse for Nagelsmann's side, after they also lost 3-2 to Turkey on Saturday.
However, the 36-year-old - who only took on the role in September and has won just one of his four games - could be in even deeper trouble after he was accused in the Austrian media of giving Trapp instructions to fake an injury.
