Michael Ballack admits he does not know how long a thigh injury will keep him sidelined for.
The Chelsea midfielder was forced off during Germany's 3-1 victory over Switzerland on Wednesday.
The Blues ace is just the latest big name to join a long list of crocked stars at Stamford Bridge.
Speaking after the game in Dusseldorf, and looking in pain, Ballack said: "It is definitely a strain, but I hope it's not serious.
"We have to wait and see in the next few days how the pain is. I hope it does not get worse.
"The injury is annoying for me.
"I've been getting through the season quite well in terms of injuries, so picking up a knock in a friendly like this is annoying and unfortunate."
i don know how he got injured. i watched the game and suddenly he was sub out
At least history did not repeat itself when he got hit in the "Ballacks"...
