Mesut Ozil is struggling to be fit for the start of Germany's World Cup campaign.
The German Football Federation has confirmed the Arsenal playmaker is suffering from a bruised knee sustained in the warm-up game against Austria last Saturday.
Ozil opened the scoring in the 2-1 defeat before being taken off after 76 minutes.
He has been training alone and missed Germany's media day on Tuesday.
Ozil is also still suffering with a lingering back problem that caused him to miss four of Arsenal's matches in May.
The 29-year-old is expected to miss Germany's final warm-up match with Saudi Arabia in Leverkusen on Friday and he has less than a fortnight to prove his fitness to Joachim Low ahead of Germany's Group F opener against Mexico on June 17.
The defending champions then face Sweden on June 23 followed by South Korea on June 27.
Germany are second-favourites to win the tournament behind Brazil.
