Michigan State University’s athletic director announced Friday he is stepping down over the scandal involving sicko sports doc Larry Nassar, who molested young female athletes at the school.

Mark Hollis told reporters at a press conference on campus that he will be “retiring” and his last day will be Jan. 31.

“Our campus, and beyond, has been attacked by evil, an individual who broke trust and so much more,” Hollis said, referring to Nassar. “As a campus community, we must do everything we can to ensure this never happens again — to make sure any sexual assault never occurs. But to do so, we must listen and learn lessons.”

Hollis continued: “Only then can we truly begin the process of healing. I have tried to do this since first learning about the abuse in September 2016.”

He called his decision to step down from his decade-long post “not an easy decision.”

“I am not running away from anything, I am running toward something. Comfort, compassion and understanding for the survivors and our community — togetherness, time and love for my family,” Hollis said.

Hollis has been the athletic director at the scandal-plagued school since 2008 and he is a 1985 MSU alum.

“I have always been a Spartan, and always will be. It’s been an absolute honor to guide the Athletic Department for the last decade.”

His announcement comes after Nassar, a former USA Gymnastics doctor who was on the faculty at MSU, was handed a prison sentence of up to 175 years Wednesday after more than 150 women accused him of years-long sexual abuse.

Hollis said that in his retirement, he will “fully cooperate” with the Michigan attorney general’s plan to investigate MSU’s role in Nassar’s widespread sex abuse and the investigation of the NCAA, “and any other investigations.”

“As a university, we must focus on the healing of the survivors and the entire community,” Hollis said.

Earlier this week, the NCAA said it was launching an investigation into how MSU handled the allegations against the twisted physician.

Just hours after Nassar’s sentencing Wednesday, MSU president Lou Anna Simon resigned.

“As tragedies are politicized, blame is inevitable. As president, it is only natural that I am the focus of this anger,” Simon said in a statement.
