The NRL said on Friday that it would not tolerate any unacceptable behaviour towards referees and other match officials.

Head of Football Todd Greenberg said the NRL would work with the Bulldogs, ANZ Stadium and authorities to try to identify people who threw bottles at match officials as they left the field of play.

Mr Greenberg said people could be banned for life from attending NRL matches.

“hat we saw at the end of today’s game was unacceptable,” Greenberg said.

“I’ll be having discussions with the club, the stadium and the authorities to ensure the appropriate penalties are handed out.

“There are a lot of marginal calls in rugby league, but what we saw today was completely unacceptable, and we will not tolerate it.

“And we’ve got to make sure we work as hard as we can to stamp that sort of behaviour out.”
