Former University of South California running back Joe McKnight was shot and killed during an apparent road-rage dispute Thursday afternoon in Louisiana, officials say.

Jefferson Parish Sheriff Newell Normand says it happened about 2:43 p.m. Thursday in Terrytown, a suburb of New Orleans.

Normand says 28-year-old McKnight was standing outside his car when he was shot by 54-year-old Ronald Gasser.

Normand says Gasser stayed at the scene and relinquished his weapon to responding officers. He says Gasser is in custody and being questioned.

Sheriff's spokesman Col. John Fortunato says they're anticipating charging Gasser, but it's unclear with what.

McKnight, who played 41 career games in the NFL with the New York Jets and Kansas City Chiefs, was 28 years old.

He is the second NFL player this year to die as a result of a possible road-rage incident. Saints player Will Smith was killed in April.
