With marquee big man Nic Naitanui (ankle) and energetic half-forward Jamie Cripps (groin) unavailable, an extended bench sees rookie ruckman Bailey Williams, rebounding half-back Francis Watson and emerging onballer Matt Allen among the possible inclusions.

Williams, Watson and Allen are on an elongated eight-man bench, along with experienced defender Will Schofield, in-form forwards Jake Waterman and Jack Petruccelle.

Also on the bench are defender Jackson Nelson and premiership midfielder Dom Sheed.

A decision on the final composition of the team will be made ahead of the team’s flight to the red centre and lodged mid-afternoon with the AFL.

Williams, 19, was drafted at selection No.35 in the ballot last November, and has been in impressive form for the WAFL Eagles, playing a shining role in the club’s victory over West Perth last week.

Watson has also been in eye-catching touch off half-back while Waterman and Petruccelle kicked 11 goals between them in the game at Mineral Resources Park last Sunday.

Allen has been consistently under consideration, while Schofield brings a wealth of experience.
