Former 49ers running back and current Australian professional rugby player Jarryd Hayne was sued Tuesday by a woman who said he raped her after the two met at a San Jose bar in 2015.

The suit, filed in Santa Clara County Superior Court, seeks unspecified damages for sexual battery, intentional infliction of emotional distress and other violations.

Efforts to reach representatives for Hayne were not successful.

According to attorneys for the woman, who was identified in court papers as “J.V.,” she was “heavily intoxicated” when Hayne brought her to his San Jose home Dec. 21, 2015, after a night of drinking and “had non-consensual sex with her.”

The woman had been a virgin and awoke the next morning with “significant vaginal pain” next to a “large pool of blood,” her attorneys, Micha Star Liberty and John Clune, wrote.

They said the pain continued, and she went to a hospital in April 2016, when staff members called police. At the time, she declined to speak with investigators, but she filed a police report the next month, her attorneys said.

San Jose police turned over their findings to the Santa Clara County district attorney’s office, which declined to file charges in October 2016. An office spokesman said prosecutors did not believe they had enough evidence for a conviction.

According to the suit, the alleged victim had been with friends at Levi’s Stadium for part of a 49ers game against the Cincinnati Bengals and later went to a restaurant and a bar in San Jose.

The group of friends met with Hayne and, “despite having minimal interaction that night,” Hayne took the woman back to his San Jose home in an Uber, wrote the attorneys.

The woman said she passed out in the Uber and vaguely remembers going into Haynes’ home and bedroom. There, she recalled “seeing a silhouette of a man” coming toward her and turning her around, the suit states.

“The man instructed her, ‘No kissing,’ and shortly thereafter she felt extremely sharp pain in her vagina,” the attorneys wrote.

The woman said she awoke the next morning draped in a single sheet and in pain. When she got home, she “became fearful of calling the police” and “worried that she would be an easy target for victim-blaming,” the suit states.

The lawsuit was filed two days before the statute of limitations was to expire.

“This is the first we have heard of this matter and the alarming allegation regarding a former employee,” the 49ers said in a statement.

Hayne was a famous Australian rugby player before joining the 49ers as a running back and punt returner in 2015. He spent time on the team as well as on the practice squad, playing in eight games before announcing his retirement from the NFL after the season.

The Sydney native has since returned to Australia to play rugby for the Parramattta Eels.
