West Coast will play host to Port Adelaide at Leederville Oval in the club's sole AAMI Community Series match after changes to the pre-season fixtures.
The Eagles were originally scheduled to face St Kilda on February 19 but all clubs will now play one game across the same weekend in the lead-up to round one with the aim of reducing travel before the home and away season.
West Coast and the Power will now meet on Sunday, March 7 at 4.10pm AWST.
All 2021 AAMI Community Series matches will be broadcast live on FOX FOOTY, Kayo and through the Official AFL LIVE App, thanks to Telstra.
Ticketing arrangements for the 2021 AAMI Community Series will be advised in due course.
The Eagles will also play a scratch match in the last weekend of February, with details of that game yet to be announced by the AFL.
