Steelers rookie running back and former Florida Gator Chris Rainey was arrested for "simple battery" (dating violence), according to the Gainesville Sun. Rainey and the victim got into a verbal argument which later turned physical, as witnesses observed Rainey slap her across the face. According to the police report, Rainey was taken to the Alachua County Jail for booking. No visible injuries were suffered by either party.
Rainey admitted to the altercation, but not slapping the witness, according to Ian Rapoport:
The arrest is not Rainey's first -- he also pled guilty to a misdemeanor stalking charge in 2010 after sending a text message to his girlfriend that read, "Time to Die B-tch."
The Steelers announced via Twitter that they waived Rainey, shortly after the news:
