Jack Martin (hamstring) has been withdrawn from the side to face Port Adelaide tomorrow.

Martin underwent scans late yesterday which revealed a low-grade hamstring that will rule him out of the remaining two games. Levi Casboult comes into the 22 to face Port Adelaide.

Zac Williams also re-aggravated his hamstring injury during yesterday’s main training session.

Williams was a chance to return to the side for next week’s Round 23 clash with GWS but will instead sit out the final game.
