Injury concern over Germany skipper Ballack
Germany captain Michael Ballack is an injury doubt for Wednesday's World Cup qualifier against Wales after sitting out training Monday.
The Chelsea midfielder picked up a knock to his right calf during Saturday's Group Four win over Russia.
A statement on the German FA website read: ''While 18 players trained in the stadium, Ballack was treated in the team hotel by DFB physiotherapist Klaus Eder.
''The 32-year-old midfielder told coach Joachim Low at lunchtime about his knock.''
The German FA have stated Ballack did not take part in training ''as a precaution''.
Ballack scored the second goal in Germany's 2-1 win at the weekend which kept them top of the group.
