Germany's players will wear black armbands during Wednesday's friendly with Australia to honour the victims of the Germanwings air crash.
The commercial jet went down in the French Alps on Tuesday with 150 people on board while travelling from Barcelona to Dusseldorf.
There will also be a minute's silence before the match in Kaiserslautern.
"It's had an impact on everyone and it overshadows everything," German Football Association president Wolfgang Niersbach is quoted as saying by BBC Sport. "As a football family, we owe it to the victims and their families to pay our respects."
It has been reported that 67 of the passengers on board were from Germany.
