NRL referees may wear cameras mounted on their heads for all matches next season if the bunker system is introduced in a move that would have enabled video referees Bernard Sutton and Ben Galea to view exactly what whistleblower Matt Cecchin had seen before awarding a controversial try to Sydney Roosters forward Kane Evans.

Cecchin stunned the 35,711 fans at Allianz Stadium and 897,000 viewers watching on Channel Nine when he stopped last Friday night's semi-final clash between the Roosters and Bulldogs and told Sutton and Galea he believed Evans had scored a try.

However, replays proved inconclusive as neither of the two camera angles made available to the video referees showed whether Evans had put the ball on or over the tryline and under the NRL's video referee policy the try was awarded as there was insufficient evidence to overturn the on-field decision.

Fairfax Media reported on Sunday that Cecchin was comfortable Evans had scored, and only wanted to check the Roosters interchange forward had not fumbled the ball, but any controversy may have been avoided if he had been wearing a camera on his head as video referees and television viewers would have had the same view as him.
