The AFL has admitted a score review official made an error during Saturday's Sydney Swans-Adelaide clash by not overturning a behind to Matthew Wright.

Wright was denied a close-range goal in the third quarter of his side's 52-point loss to the Swans, when the goal umpire deemed the Crows' midfielder did not get boot to ball.

The officiating umpire referred the decision to the video reviewer. Although replays appeared to capture Wright's toe-poke brushing the ball before it crossed the line, the goal was ruled an umpire's call and resulted in one behind.

On Monday night, League Football Operations Manager Mark Evans said the score review system had failed.

"That's an error, isn't it?" Evans told Fox Footy.

"We've had 105 reviews so far this year. On about 20 per cent of occasions we've changed the score, so 25 times we've changed the score - we should've changed it 26 times."

Evans also said the AFL was set to improve its video review system at all venues next season.

In a separate incident in Round 18, Gold Coast onballer Luke Russell kicked what appeared to be a goal during the third quarter of the Suns' draw against West Coast at Metricon Stadium.

Eagle Matt Rosa made a last-ditch effort to touch the ball on the goal line, and the goal umpire ruled Rosa touched the ball.

The decision was upheld by the score review official due to the lack of camera angles – including goal-line technology – available at the venue.

The decision was criticised by Suns coach Rodney Eade post-match.

Evans said the League would introduce the same goal review technology at all AFL grounds to ensure more camera angles were available at venues.

"We'll roll that out. It is a matter of efficiencies and efficient use of money," he said.

Evans proposed the idea of creating an in-house "bunker" that would see all score reviews adjudicated from a central location.

"Somewhere in the future, I actually like the idea that it comes back into a central bunker and we'd have our very best reviewers review every game," he said.
