UPDATE: Penn State released additional responses to lawsuit filed by a former player.

Penn State football coach James Franklin retaliated against former player Isaiah Humphries after he reported violent hazing by other members of the team, Humphries contends in a federal lawsuit filed Tuesday.

Humphries, who was recruited to the Nittany Lions but later left the program, is suing Franklin and ex-teammate Damion Barber of Harrisburg in U.S. Middle District Court.

Humphries also names three other players, Micah Parsons, Yetur Gross-Matos and Jesse Luketa, as participants in the alleged hazing. He claims that, among other things, the hazers invoked the name of disgraced former coach Jerry Sandusky, who is in prison for molesting young boys.

In a statement, the university said that “Penn State police investigated related allegations and forwarded the results of that investigation to the Office of the Centre County District Attorney (DA). The DA reviewed the case and decided that no charges would be pursued.”
