Adelaide has confirmed one change for Sunday’s clash with West Coast at Optus Stadium.

Experienced ruckman Sam Jacobs returns to the senior side to tackle the Eagles as a direct swap for Reilly O’Brien.

Jacobs was named as the starting ruckman on Thursday and is set to take on the bulk of the ruck duties after the Crows’ match committee opted against playing two genuine ruckmen.
