GAINESVILLE, Fla. (AP) - Pittsburgh Steeler rookie running back Chris Rainey has been arrested in Florida, accused of slapping his girlfriend.

Gainesville police officers charged Rainey Thursday morning with a single count of misdemeanor simple battery. He was taken to jail for booking.

Police say in a news release that Rainey was arguing with his girlfriend over his cellphone. His girlfriend got into a vehicle and the ex-Florida Gator tried to pull her out.

Witnesses told detectives that Rainey slapped his girlfriend of nine months across the face and then chased her when she ran away with his phone in her purse.

Rainey's agent, Joel Segal, didn't return a phone call for comment.

The 24-year-old fifth-round draft pick played in all 16 games for the Steelers, mostly returning kicks. He returned 39 kickoffs for 1,035 yards.
