"The Bakersfield Californian reported Tuesday that Arizona Cardinals linebacker Joey Porter has accused a California Highway Patrol officer of unlawfully striking him the night the former Steelers star was arrested on charges of drunken driving, battery on a peace officer and resisting arrest.

Porter's allegation is under investigation in the context of the whole incident, Sgt. Larry McGuire said Tuesday. He also said there is no internal affairs complaint or investigation against Officer Jeritt Greer, who arrested Porter early Saturday morning at a Taco Bell parking lot.

Greer has a pending drunken driving charge against himself stemming from an October arrest, according to the Kern County Superior Court website."
