Semi Radradra has reportedly denied allegations he kicked his ex-partner in the stomach when she was nine months pregnant.
The NRL star had an interim apprehended domestic violence order taken out against him on Wednesday, after his former partner, Perina Ting, reported the claims to police on Tuesday night.
The incident is one of three alleged to have been committed between September 2014 and April 2015 by the Parramatta winger against Ting before the couple separated in February.
However Radradra's sister, Vaseva Waqavatu, said the Kangaroos representative was upset by claims which he said were false.
"He said it was all bulls**t and made-up stories we don't believe he could do something so common," Waqavatu told News Corp.
The matter is listed for Parramatta court on Tuesday, while Radradra is expected to be back in the country from Fiji by Friday to play against Cronulla the following night.
