Parramatta Eels have informed the NRL Integrity Unit and vowed to assist the authorities after they were made aware of allegations of assault made against Semi Radradra.
Radradra is alleged to have assaulted his former partner, who reported the wing to the police claiming she was attacked in 2014 and last year.
The Eels said in a statement: "The Parramatta Eels are aware of allegations made on Tuesday concerning winger Semi Radradra.
"The Eels have informed the NRL Integrity Unit, and the club will continue to work with the relevant authorities.
"As these allegations have been referred to police, the club will be making no further comment at this time on this particular matter.
"The Parramatta Eels have, through their welfare staff, been providing ongoing programs and services to Semi Radradra and his family, and will continue to offer support as required to all staff, players and family members at the club.
"As a national sporting club, the Eels are committed to promoting education, counselling and support around the issue of family violence, both publicly and within the Eels organisation."
The 24-year-old has been linked with code switch to Top 14 side Bordeaux-Begles, but the Fiji-born flyer's management last week said he will remain with the Eels until the end of next season.
