ADELAIDE has made one change to its team for Showdown XLI.

Ruckman Sam Jacobs returns from injury for the Crows, replacing Riley O'Brien, who has been omitted.

Port Adelaide has been forced to make three injury-related changes, with Chad Wingard (hamstring), Charlie Dixon (ankle) and Logan Austin (groin) replaced by Jake Neade, Jay Schulz and Jimmy Toumpas.

Saturday night's Showdown is a sell-out, with three-game memeberships now the only way to buy access to the game. 

Memberships can be purchased at weareportadelaide.com.au
