Chelsea midfielder Michael Ballack had surgery to remove swollen nerve tissue in both feet on Friday and will be out for two weeks, the German Football Association (DFB) said in a statement.
Ballack, the Germany captain, had the brief surgery in an Augsburg clinic after consulting with his Premier League club, the DFB said. The surgery went "well and without complications."
"Michael Ballack complained again of strong pain in both feet after the World Cup qualifying game against Wales on Wednesday," German team doctor Hans-Wilhelm Mueller-Wohlfahrt said in the DFB statement.
"An MRI on Thursday confirmed our suspicion of neuroma so after consultation with the club doctor, manager and coach of Chelsea it was decided to operate on both feet."
If all went well, Ballack would be able to resume training in two weeks, Mueller-Wohlfahrt added.
