David Salmon allegedly hit and seriously injured 44-year-old jogger Kelly Mahan at Madison and Halsted on Aug. 3.
Mahan's family told ABC7 she was released from the hospital by Wednesday.
She survived a brain aneurysm a few years ago and running turned into her therapy, eventually competing. But for now, she is facing a series of medical hurdles.
Salmon has been charged with felony counts of failure to report an accident and leaving the scene of an accident resulting in injury.
Salmon has been relieved of his police powers and placed on administrative duties.
The sheriff's office said it launched an ongoing internal investigation of Salmon, which may result in disciplinary action up to and including termination.
