NRL star Jarryd Hayne has vehemently denied he raped a woman in the United States in 2015 when he was playing gridiron with the San Francisco 49ers but admits he "hooked up" with her, according to court documents.
The woman has filed a civil complaint in California which alleges Hayne took her back to his San Jose home after a 49ers game and raped her when she was drunk.
Documents lodged in a County of Santa Clara court state the woman had previously met some of Hayne's friends when working at a restaurant and a group went out drinking after the December 20 game.The documents say Hayne later took the woman, who is referred to as Ms V, home in an Uber and she passed out in the car "due to her extreme level of intoxication".
The victim says she was a virgin at the time of the alleged attack.
Her lawyer, John Clune, said that at the time his client was so intoxicated she was "unable to consent to sexual intercourse".
"Mr Hayne brought our client back to his home, approached her in the dark, turned her around as to not face him and told her 'no kissing'," Mr Clune said in a statement.
"He then had non-consensual sexual intercourse with her."Hayne said he had previously provided "all reasonable assistance" to authorities after the woman went to police in May 2016.
"He unequivocally and vehemently denies the allegations which are the subject of the civil complaint," the player's Sydney lawyer, Ramy Qutami, said in a statement on Wednesday.
The court documents reveal the woman took Hayne's "undergarment" after the alleged rape in case she needed proof of the incident. AAP understands it's now with local police.
The woman said she had vaginal pain for months and went to the emergency department in April 2016.
"The hospital called the police but the plaintiff declined to speak with them," the court documents state.
A month later she reported the matter to police but, after an investigation, the Santa Clara County district attorney's office told the woman "there was not enough evidence to prove the crime of rape beyond a reasonable doubt".
In the statement of complaint, the plaintiff says she didn't immediately report the incident to authorities because she feared being discredited or blamed.
Instead, she asked a friend to speak with Hayne and when he reportedly said "nothing had happened" she contacted him direct via Instagram. He then admitted they had "hooked up".
AAP understands Hayne would be expected to return to the US if the woman is granted a jury trial as she's demanding.
The action is for sexual battery, battery, gender violence, intentional infliction of emotional distress and negligence arising from the alleged rape.
The woman is seeking monetary compensation for "emotional pain, anguish and severe distress".
Hayne's NRL club, Parramatta, said they were unaware of the allegations until Wednesday.
"As with any legal matter it is important we follow due process and ensure we review all relevant information available, including giving Jarryd the opportunity to respond," the club said in a statement.
The NRL said the organisation's integrity unit would monitor Hayne's case.
"We note the police in the United States did not proceed with any criminal proceedings but we will review the information available and continue to monitor the civil case," a spokesman said.
A San Francisco 49ers spokesman said "this is the first we have heard of this matter and the alarming allegation regarding a former employee".
