Podolski also battling to shake off knock ahead of Portugal game
Germany will not take any risks with Torsten Frings' fitness and will make a late decision on whether the midfielder can face Portugal.
Frings sustained a fractured rib during Germany's 1-0 win over Austria on Monday night, although he was initially unaware of the injury.
He is battling to be fit for Thursday's Euro 2008 quarter-final against Portugal in Basel and he will be given every chance to make the starting line-up.
"We won't decide until just before we have to hand in the team sheet," said Germany's team manager Oliver Bierhoff.
Eager to play
"If the medics say there is even a slight chance of a serious injury then we won't risk it.
"But I have to give credit to him. He's eager to play."
Lukas Podolski is also an injury concern for Germany after picking up a calf problem in the final Group B encounter with co-hosts Austria.
The Bayern Munich striker did not train on Tuesday, but Bierhoff feels Podolski is making progress in his recovery from the injury.
Bierhoff added: "Things have improved greatly over the last 24 hours, but with muscle problems you never know."
