John Hopoate has been hit with a four-match ban and is expected to miss more time, after being charged with three other offences relating to incidents during a match in the Manly District Junior Rugby League competition.
Hopoate - who was playing for the Narraweena Hawks against the Forestville Ferrets - was heard abusing and threatening opposition players on the field.
The former NRL veteran repeatedly swore at players and told them he would "bash them", before being sent off by the referee.
Hopoate was handed the four-match ban for punching an opponent.
He then stopped momentarily beside the Ferrets bench for another word, before being moved on.
The three other offences have breached the NSWRL's Code of Conduct, and will be discussed by the NSWRL Conduct Review Panel on Wednesday night, to see determine the correct punishment, if any, for Hopoate.
"I am confident our Conduct Review Panel will deal with the matter appropriately," NSWRL Chief Executive David Trodden told nswrl.com.au.
"NSWRL will make further comment after the judiciary process has been completed."
