The AFL will continue to set a 10m protected area around the mark after trialling the rule during the pre-season.
protected zone is designed to make it easier for the player with the
ball to assess his options and it will now be used in regular season
"It is the general view that the ability of teams to move
the ball has improved with the larger protected area," said AFL
operations manager Mark Evans.
Umpires have also had a stricter
interpretation of illegal tackles and deliberate out of bounds decisions
during the NAB Challenge.
