Germany coach Joachim Low will give Mesut Ozil as long as possible to prove his fitness in midweek.
The Real Madrid man picked up an ankle injury in Friday's 3-0 victory over Turkey and is now a major doubt for Tuesday's clash with Kazakhstan.
The 21-year-old playmaker is expected to sit out training on Sunday in order to rest the problem before flying out with the rest of the squad on Monday.
Low has then requested that Ozil undertake a late fitness test before he finalises his plans for Germany's latest Euro 2012 qualifier.
"National coach Joachim Low has arranged with the doctors and physical trainers to give him a fitness test in the final training session on Monday," said the German Football Federation in a statement.
Ozil is optimistic regarding his chances of shaking off the knock and hopes he will be given the opportunity to face the Kazaks.
"It still hurts, but I trust in the swift treatment I have been given by the national team doctors and physios," he said.
"I hope that I can get fit again quickly."
