Embattled NRL player Greg Bird will face two new charges when he returns to court next month over an alleged attack on his girlfriend.

Bird, 24, was charged with one count of maliciously inflicting grievous bodily harm after allegedly glassing his girlfriend in the face at his Cronulla apartment on August 24.

Without naming Bird, police said his lawyer had been advised additional charges of public mischief and false accusation would be laid in Sydney’s Downing Centre Local Court on October 9.

The Cronulla Sharks five-eighth was suspended by his club after the incident involving his American girlfriend Katie Milligan, whom police said suffered a fractured eye socket and required surgery for glass wounds.

It is alleged she and Bird had argued at his Boorima Place unit before she was struck.

Ms Milligan, 24, earlier this month said she remained “absolutely 100 per cent” behind Bird.

At the time, the law student said she did not support the apprehended violence order against Bird – which was taken out by police on her behalf.

Her lawyer, Philip Sim, said she was holding up well but was missing Bird.

Bird is expected to make an application to vary his bail conditions when the matter returns to court on October 9.

On that date, he is also due to answer a Field Court Attendance Notice for common assault relating to an alleged incident involving another woman at a Cronulla nightclub in January this year.
