Canterbury coach Des Hasler has leapt to the defence of NRL referees, blaming the media for heaping more pressure on under-fire whistleblowers.
Match officials have been in the firing line since last week's State of Origin opener in Melbourne following some contentious decisions that upset New South Wales.
Referees chief Bill Harrigan is involved in showdown talks with the NRL in the fall-out from the game with his future believed to be in doubt.
And Hasler said referees do not receive the same protection as officials in other sports.
"The referees in AFL, NBA and NFL football are more revered," Hasler said. "To a certain extent referees are more persecuted in our game and you blokes [the media] have a fair bit to do with that. I back it up by saying it is part of the culture of rugby league to give it to the referee."
