Kate Fallon: See the gruesome head injury suffered by girl, 17, who was allegedly bashed by a female footy star over a food delivery gone wrong

An NRLW player has been charged with allegedly assaulting a teenager inside a Sydney eastern suburbs unit block over an argument relating to a food delivery order gone wrong.

Parramatta Eels player Kate Fallon, 20, was charged after emergency services were called to an apartment complex at Namatjira Place, Chifley at about 1.30pm last Tuesday.

Paramedics treated a 17-year-old girl for injuries to her head before she was taken to Prince of Wales Hospital as a precaution and released.

Ms Fallon was arrested at the scene and charged with assault occasioning actual bodily harm.

She was granted bail and will appear in Waverley Local Court on August 14.

The girl's father told 2GB's Ben Fordham that the alleged altercation occurred when she ordered $70 worth of UberEats and when it did not arrive, she knocked on the door of another flat in the building.

He described her injuries as 'gruesome' and claimed Fallon used an unknown object in the alleged attack.

'She's not too bad considering what she's been through, you know what I mean,' he said of his daughter, adding that she needed stitches in the wound.

'And the funny thing about it is I haven't received a call from anyone, the NRLW, Parramatta or even the Integrity Unit.

'What about the wellbeing of my daughter? 

'It's appalling. You know, you have a look at it, one or two inches and it hits you in the temple.

'And that's how close it was. As you can see in the pictures, it's pretty gruesome.

'My daughter, she's a pretty tough cookie, but to go through this...'  

Parramatta said in a statement that they were aware of a matter involving one of their NRLW players.

'The club advised the NRL integrity unit as per our normal process,' the club said.

'As it is a police matter, the club will not be making further comment at this time.'

NSW Police released a statement on the matter on Wednesday night.

'NSW Ambulance paramedics treated a 17-year-old girl for injuries to her head,' it read.

'She was taken to Prince of Wales Hospital as a precaution; she was treated and released.

'Officers from Eastern Beaches Police Area Command arrested a 20-year-old woman at the scene.

'She was taken to Maroubra Police Station and charged with assault occasioning actual bodily harm.'

2GB reported that Fallon has been named as a reserve for Parramatta as they prepare to play their first game of the NRLW season against Brisbane on Saturday. 

She is due to front Waverley Local Court on August 14.
