The Pittsburgh Steelers have fired running back Chris Rainey after he was arrested for allegedly assaulting his girlfriend in Gainesville, Florida. The arrest went down after someone witnessing Rainey attacking his girlfriend and they called 911.

According to a release from the Gainesville, Fla., Police Department, officers were called regarding an argument between a man and a woman that had turned physical.

Officers arrived and identified Christopher J. Rainey, as the male involved. Witnesses told officers that Rainey and the victim got into an argument over Rainey’s cellphone. The female victim entered the vehicle of Rainey’s roommate, and Rainey confronted her on the passenger side of the vehicle, and began pulling her out of the vehicle. Witnesses then observed Rainey slap the victim across the face with an open hand. Both Rainey and the female victim then fell to the ground. The victim was able to run away, but Rainey chased after her because his cellphone was in a bag the victim was carrying. Rainey grabbed the bag again, and they both fell to the ground again. Neither party suffered visible injuries from the encounter. Multiple witnesses confirmed the incident.
