GREATER Western Sydney coach Leon Cameron may be punished by the AFL for approaching the emergency umpire during Sunday’s loss to Fremantle at Domain Stadium.

Twice during Sunday’s clash, the Giants coach stormed from his box during play to personally query the fourth umpire.

Cameron said post-match he would wait until Monday to speak to AFL umpires boss Wayne Campbell, something the AFL Coaches Association said should’ve been his only form of communication.

The Giants lost the free kick count 16-20 during the 21-point loss to Freo.

On Monday, League CEO Gillon McLachlan said it was "not a good look" for the game.

McLachlan said the League would address the issue with Cameron.

"He’s apologised to the umpires - (AFL football operations boss) Mark (Evans) I think will make a decision tomorrow," McLachlan told Channel Nine.

"It’s not a good look, he shouldn’t have done it.

"He (Cameron) has acknowledged that and spoken I think with the umpiring department and even with the umpires he was referring to. There’s got to be a level of accountability for that behaviour."

The AFLCA added Cameron had set a poor example for coaches around the country.

"AFL coaches understand that umpires' rights to work free from interference on match day are sacrosanct," AFLCA chief Mark Brayshaw told Channel Nine.

"Leon engaging with the emergency umpire on Sunday at Domain Stadium set the wrong example for community coaches across the country.

"We would prefer that Leon call Wayne mid-week to get any clarification he needs and believe he’ll do so next time."

Fremantle coach Ross Lyon said it was "surprising" to see Cameron head to ground level and that it was a bad look for the game.
