The AFL has blamed technical reasons for the controversial score review blunder in Fremantle’s four-point win over Collingwood.

Michael Walters’ snap at goal was clearly touched by Chris Mayne in the third quarter, but the score reviewer did not have access to that footage.

Instead, the goal was allowed based on footage from the goal line.

Confirmation of Saturday’s error will come as cold comfort to the Magpies.

“The score review officer reviewed the vision available at the time and based on this vision supported the umpire’s decision that a goal had been scored,” the league said in the statement.

“Due to technical reasons, the subsequent vision shown by the broadcaster was unavailable to the score review officer at the time of review.

“The AFL acknowledges that based on the additional broadcast vision the ball was touched by Collingwood player Chris Mayne.

“The AFL will continue to improve the score review process to ensure that all vision captured by the broadcaster is available to score review officers at the time of the review.”
