THE NRL’s referees have copped plenty of flack this season, but even their latest blunder made the match officials and players smile.

Shortly before halftime in Friday night’s blockbuster clash between South Sydney and Melbourne, Campbell Graham and Josh Addo-Carr contested a high ball with Graham coming up with a knock on.

“The bunker’s treading on eggshells, aren’t they?!” Fox Sports commentator Brenton Speed exclaimed.

“They put up try on the screen and the Bunnies fans are celebrating, but it is no try.

“What’s this red button mean?”

Of course, the mix-up wasn’t missed by many NRL fans on social media.
