HANNOVER, Germany -- Hannover captain and American defender Steve Cherundolo needs more surgery on his left knee.
The Bundesliga club says Cherundolo will have the surgery on Friday. The 34-year-old had the same knee operated on in February.
Cherundolo says "the injury and the timing are frustrating," but he hopes to be able to practice soon without pain.
He felt pain in the knee after a collision on Tuesday as Hannover began preseason training.
Cherundolo played only 20 games last season but set Hannover's record for Bundesliga appearances with 300.
