Forward Jason Porplyzia and defender Sam Shaw are late withdrawals from Balfours Showdown XXXII at AAMI Stadium on Sunday afternoon.

Porplyzia (strained deltoid) and Shaw (hamstring tightness) were unable to complete the Crows' light training run on Saturday morning and have been replaced in the selected 22 by Andy Otten and Rick Henderson.

Henderson will start as the substitute.

Port Adelaide has also made a late change, recalling David Rodan at the expense of tall forward Daniel Stewart. Debutant Aaron Young will start in the green vest for the Power.
