Danario Alexander doesn't know where his comeback will happen.

His focus now is making sure it does.

The Chargers wide receiver is rehabbing a torn anterior cruciate ligament suffered Aug. 6 in practice. The ACL tear to his right knee came during a contract year after having undergone five various operations to his left in recent years.

Alexander erased any doubt about his intentions to return from the latest knee operation.

He had reconstructive surgery on Aug. 15.
