"While deep consideration was given to forcing a set number of players to be anchored in zones at each stoppage, the AFL baulked at introducing such drastic rules for 2021.
It will, though, implement such measures in the newly formed VFL and East Coast second-tier competition, with a minimum of players from each team to be positioned inside each 50m arc - including one per team in each goalsquare – at all kick-ins and boundary throw-ins.
Breaches of this rule will result in 50m penalties. The AFL will monitor the workings of this rule and will be prepared to introduce it to the 2022 AFL season."
