The major hurdle preventing the AFL using video technology to assist in close goal calls is the way this would increase stoppages in play.

The league has already ruled out video referrals in this year's finals despite Geelong being denied a clear goal in their 32-point loss to Collingwood at the MCG on Saturday night.

Geelong's Shannon Byrnes was denied a major because the goal umpire ruled he had overstepped the goal line before he kicked the ball, although replays clearly showed he had not.

The blunder, and two goal errors in Friday night's Carlton-Essendon game, prompted a call from Magpies coach Mick Malthouse for technology to be used as it is in close decisions in tennis, cricket and rugby league.

Malthouse said close decisions could be reviewed in 15 seconds and fans would not mind a delay if it meant the right decision was made.

But an AFL spokesman said the concern over a delay in play was the reason the laws of the game committee had previously decided against using technology.

"We always want play to be continuous, so that's why in the past it has never got through," the spokesman said.

The laws of the game committee could next month discuss using video technology for next season.

Geelong coach Mark Thompson was against the introduction of technology because of the costs involved and to prevent the game being over-officiated.

The Cats would have led by 12 points in the third quarter had Byrnes' kick been awarded a goal but Thompson said the decision had no bearing on the result.
