An official announcement containing the full details of Round 23 was released by AFL House on Monday night.

The final set of regular season clashes will commence when a pair of premiership fancies in the Western Bulldogs and Port Adelaide meeting at Marvel Stadium on Friday night.

This contest is a crucial one for Luke Beveridge's Pups, as only a win will see them secure a top-four position following their upset loss to Hawthorn in Round 22.

24-hours later, Geelong and Melbourne will meet to decide who will be crowned as 2021's minor premier.

After deliberations about whether the fixture would take place at the MCG or down the highway in the Pivot City,  the league has locked the GMHBA Stadium as the venue.

The Redlegs have not finished a home-and-away season atop the ladder since 1964 - the same season they last claimed the premiership cup.

St Kilda's final match against a potentially finals bound Fremantle side has been sent across Bass Strait to Hobart's Blundstone Arena after originally being listed as TBC.

This move has reportedly been raised due to the Dockers desire not to play an east-coast game that would start at 10:15am Perth time.
