AFL CHIEF executive Andrew Demetriou has indicated that the rule requiring a field umpire to signal "all clear" to the goal umpire before a score is registered is facing review at season's end.

The issue came under scrutiny last week when goal umpire Tristan Symes failed to signal a behind because he did not receive the “all clear” from the field umpire as the ball was quickly kicked out from goal in last week’s Swans v Crows clash.

Speaking to the Herald Sun newspaper, Demetriou questioned the practicality of the signal, and stated that the practice may need to be re-assessed.
 
“That is something we may have to look at,” he said.

“Given there is communication out there between the umpires, I am not quite sure whether we need the goal umpires seeking the field umpires for the all clear, particularly in the mayhem of the ball being brought out quickly.”

A contrary argument would see necessity for the field umpire's signal to be kept in the game, given the rate of goal square infringements and the large packs that can obstruct an umpire’s view.

Demetriou’s comments continue the fallout from the mistake which cost the Swans a behind and cannot be rectified as it was never signalled by the goal umpire.

“There was a simple error which could have been a more serious one by the umpire,” Demetriou said.

The missing behind may be raised again if it effects either Adelaide or the Swans in the jostle for ladder positions.
