The South Sydney Rabbitohs have released a statement which says they will investigate allegations of player misbehaviour from earlier in the year.
The incident, which allegedly took place in May, was reported by News Ltd publications on Friday morning.
The Rabbitohs said a thorough investigation would be undertaken in conjunction and in close co-operation with the NRLs Integrity Unit.
"Since receiving contact details [on Thursday] night for the female involved, Rabbitohs officials have attempted to make contact via phone and email," the statement read.
"The Rabbitohs take any allegations of player misbehaviour very seriously and will not be making any further comment until the completion of the investigation."
Rabbitohs coach Anthony Seibold said he would prefer to not be talking about the incident but rather their semi-final with St George Illawarra on Saturday night.
"I would rather be talking about tomorrow night," he said.
"I appreciate the interest from the wider community around this.
"There's an investigation under way and like everyone else I'm keen to see it play out and be resolved appropriately.
"With regards to the accusations, our club treat the accusations seriously, as do the NRL Integrity Unit. In consultation between the Integrity Unit and the club I understand the investigation is ongoing. Outside of that there's no other comment I can make this morning.
"It's a little bit of chaos thrown in front of us. Of course it's not ideal. We've got the players in here this morning and our last practice before a semi-final game. All I can do is control what we do inside the change rooms and how we prepare on the park."
With regards to on-field matters, Seibold said star duo Adam Reynolds and Greg Inglis had trained strongly and would suit up against the Dragons.
"[Reynolds] is a little bit sore with his shoulder but he's got no dramas about playing tomorrow night, he'll get a needle like probably a couple of other players from both sides have to at this time of year and he'll crack on with it," Seibold said.
"[Inglis] trained both sessions this week. This morning's just an individual session so the players choose what they need to do to prepare best for the game. Greg's trained both sessions, he's got a bit of a bruise to a rib, I don't know if it's rib cartilage for Greggy but he's all good to go."
