Prosecutor's presented the case to the grand jury on Thursday. Manziel faces up to a year in jail and a $4,000 fine.
The charge stems from an altercation Manziel had in February with his ex-girlfriend Colleen Crowley, who obtained a protective order again him shortly thereafter.
The indictment came despite a civil settlement being reached between Manziel and Crowley, according to KRLD-AM. In a sworn affidavit, Crowley said Manziel hit her and threatened to kill them both. Her lawyer said he struck her so hard she suffered hearing loss.
