Olsen, the younger brother of Carolina Panthers tight end Greg Olsen, was charged in February for the suspected attack on a female in an off-campus apartment.
The grand jury handed up indictments on three counts of second-degree rape, two counts of assault on a female and one count of second-degree sexual offense.
Prosecutors said Olsen texted a woman and threatened to kill her. They said he raped her, punched her in the face and also threatened to kill himself, wrapping a phone charger around his neck.
The accuser called the police and was treated for injuries at a hospital. The report said she had bruises and scratches.
Olsen has been suspended from UNC-Charlotte athletics.
