In a federal lawsuit filed Tuesday, Humphries accused defensive end Yetur Gross-Matos and linebackers Micah Parsons and Jesse Luketa of being the ringleaders of the hazing. Humphries said he was met with threats such as, "I'm going to Sandusky you," referring to the former Penn State assistant coach who's serving 30-to-60 years in prison for sexually assaulting boys at the school.
Humphries said the hazing was observed by coaches and that they didn't intervene. He added that both he and his father complained about the incidents but were ignored.
Humphries transferred out of the program in November 2018 and landed at Cal.
He said coaches gave him poor reviews to other schools when they learned he planned to transfer and that he was forced to perform drills that coaches knew he'd fail.
Penn State released a statement Tuesday afternoon that an internal investigation was already conducted on the matter.
"The university has established processes in place for responding to claims of potential misconduct. In accordance with our processes, the Office of Sexual Misconduct Prevention and Response and the Office of Student Conduct carried out investigations of the plaintiff's claims independent from Intercollegiate Athletics," read the statement, obtained by Maddie Aiken of The Daily Collegian. "In addition, 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."
