The NRL is investigating Warriors forward Josh Curran over an incident at a licensed venue in Port Macquarie on NSW's mid-North Coast over the weekend.
The Warriors released a statement on Tuesday afternoon confirming they had reported the matter to the NRL integrity Unit but would not comment further until the league's investigation has been finalised.
It comes as the NRL weighs up whether to stand North Queensland recruit Luciano Leilua down after he was charged on Monday with assaulting a woman known to him.
Leilua is due to represent Samoa at the Rugby League World Cup but NRL sanctions could impinge on his ability to line up at the event, which begins in England later this month.
