NRL CEO Dave Smith said he was disappointed with yesterday's events, which would not be tolerated in rugby league.
Mr Smith said the events both on and off the field would be considered thoroughly and carefully.
"These matters were serious and extremely disappointing for the entire game and do not reflect the game's values both on and off-the-field," Mr Smith said.
"We will be working with the police, ANZ Stadium and the Bulldogs to carefully review all matters regarding fan behaviour.
"Under the game's code of conduct, there are a range of sanctions available to consider, which we will do in a thorough and considered way."
