The AFL commission announced games will revert back to normal quarter lengths next season.
The COVID-19 pandemic that forced a fixture squeeze resulted in the league reducing quarter lengths to 16 minutes plus time on in 2020.
But quarters will revert back to the normal 20 minutes plus time on in 2021.
Teams will receive six-minute breaks for quarter-time and three-quarter time, while halftime will be 20 minutes.
There will be a break of 50 seconds after each goal.
