West Coast and Collingwood will write another chapter in a storied recent finals history when they face-off in a blockbuster elimination final next Saturday night.

The Magpies' 16-point loss to minor premier Port Adelaide on Monday night confirmed Nathan Buckley's men would finish eighth on the ladder, meaning they will pack their bags and head west to Optus Stadium.

Bouncedown has been locked in for 6.10pm AWST on Saturday, October 3. 

Tickets will go on sale Tuesday, September 29 via Ticketmaster. Eligible members will be emailed ticketing information in the coming days.

The Magpies will fly west this Friday and both sides will have finished their respective quarantine periods by game day. 

This will be the third post-season clash between the 2018 Grand Finalists in three seasons, and it looms as another epic encounter.

The Eagles have won the past two finals against the Pies, getting up in a cliffhanger qualifying final at Optus in 2018 by 16 points in front of 59,585 fans and, of course, their famous Grand Final victory three weeks later at the MCG. 

West Coast notched a resounding victory over Collingwood in the sides' only meeting this season, running out 66-point winners in round eight. 

The winner of next Saturday night’s contest will square off against the loser of next Thursday's first qualifying final between minor premiers Port Adelaide and Geelong for a place in a preliminary final.
