Germany could go into Sunday's UEFA Euro 2008 final against Spain without Michael Ballack as their captain is receiving treatment for a calf injury.

The 31-year-old was a notable absentee on Saturday as the team were practicing at the Ernst-Happel-Stadion on the eve of the final showdown.

"The muscles has tightened and we'll have to wait and see how things develop," explained coach Joachim Loew.

"Our medical people are working around the clock to give him a chance to play."

According to the German soccer federation, Ballack hurt his right calf Friday and also sat out the team's training session that day.

Loew also said that should the midfielder not recover, then either Tim Borowski or Bastian Schweinsteiger will assume his place.

"He's team captain and an extremely important player, but if he is not fit then someone else will take his position," the 48-year-old added.

"Having a squad of 23 means those who haven't played much are highly motivated. We'll have to cope, we will find a solution. I've not counted Michael Ballack out yet though. There is still a chance."
