Bundesliga leaders Hamburg will be without full-back Marcell Jansen for up to six weeks due to a thigh strain picked up while on international duty.
Jansen was injured in training during the build-up to Germany's World Cup qualifying victory over Russia last weekend.
He joins Netherlands midfielder Nigel de Jong on the injury list at the AOL Arena.
"His muscle tear is more serious that first thought," revealed Hamburg coach Martin Jol. "He will be out for three to six weeks."
Meanwhile, Wolfsburg are set to be without Italy international Cristian Zaccardo for the next two weeks after the defender suffered an ankle injury in a friendly against Greuther Furth on Monday.
The 26-year-old underwent tests on Tuesday which showed that he had sustained a slight tear to the ligaments in his right ankle.
On the financial front, Bayern Munich general manager Uli Hoeness says his club have nothing to fear from the worldwide slowdown which has sparked trouble at some clubs.
He told Bild: "I think German football has less to fear than the game in certain other countries.
"The lights could go out in one or two cases, but it won't affect the big players. There's no risk to us whatsoever."
The furore over striker Kevin Kuranyi's walkout at half-time of Germany's 2-1 win over Russia at the weekend rumbles on, with national team general manager, Oliver Bierhoff, having his say.
Kuranyi has apologised for his behaviour, with Bierhoff having some sympathy for the Schalke frontman.
He said: "I have seen a bit of what Kevin said and you can see how tough it has been for him.
"We can understand it, but not what he did against his team-mates. That, we cannot accept.
"He always seemed to be fine when he was with us and I wish him all the best."
