Parramatta Eels' Semi Radradra pleaded not guilty to three assault charges at Parramatta Local Court on Tuesday.
Radradra's former partner reported the wing to the police alleging she had been attacked in 2014 and last year.
The 24-year-old confirmed his decision to contest one charge of assault causing actual bodily harm and two counts of common assault on Tuesday.
"In relation to the matter of Semi Radradra Waqavatu ... pleas of not guilty entered to sequences one, two and three," magistrate Theo Tsavdaridis said.
The matter has reportedly been adjourned until the next hearing on August 16.
Following his court appearance, Radradra went to training having been named in the line-up to face Sydney Roosters on Friday.
Eels team-mate David Gower was impressed by the Australia international's work-rate given his situation.
"He was good. Obviously there are extenuating circumstances for him but he knows when he gets to training he's got to do a job for us and he did that today at training," said Gower.
"My understanding is that he's pleaded not guilty and as far as we're concerned and as far as the game needs to be concerned, it's innocent until proven guilty.
"And when the time comes for the court case, the appropriate steps will be taken."
