Miroslav Klose is doubtful for Germany's third-place play-off clash with Uruguay after suffering a back injury.
The 32-year-old sustained the problem in Wednesday's 1-0 defeat to Spain in their World Cup semi-final in Durban.
German assistant coach Hansi Flick confirmed Klose, who has scored four goals at the finals, is struggling to be fit for the showdown with Uruguay.
"Klose has problems with his back," said Flick.
"He was hurt in an aerial duel, and we are hoping that he will be OK for the match."
Germany captain Philipp Lahm is also struggling with a knock, but the full-back insists he will be fit in time to take on Uruguay.
"Do not worry, it would astonish me if I wasn't ready for this match, it is not as serious as all that," said Lahm.
"And also I have time to rest and the body can absorb the pain during a day off."
