Czech Republic manager Michal Bilek is sweating over the fitness of team captain Tomas Rosicky.
The Arsenal midfielder picked up an Achilles injury during Tuesday's 2-1 win over Greece and is now a worry ahead of their final group match with Poland on Saturday.
Czech Republic were leading 2-0 when the 31-year-old came off at half time, and Bilek is hoping to have his skipper available for the crucial final day of Group A matches.
"We will see on Wednesday what the extent of the problem is," Bilek said.
"He's important. We missed him in the second half as he's a key player."
Czech Republic need to defeat Poland in their final Group A match on Saturday to qualify by right but can also qualify if they draw against the co-hosts and Russia win or draw.
