Cam Zurhaar has been named to play his fourth game of the season, and eighth of his career, in the clash with Geelong on Saturday.

The young, powerfully built small-forward will replace an injured Jed Anderson in the side, who failed to convince the match committee of his readiness after experiencing hamstring tightness in the early stages of North's victory over Brisbane in Round 11.

The Roos are clearly taking a no risk approach with Anderson, who has had a history of injuries. The club will use the bye round next week to ensure he's fully fit and ready to play against the Bulldogs in Round 14.

Zurhaar's VFL form has been strong, but the 20-year-old's season has been somewhat interrupted, acting as the traveling emergency on several occasions in the AFL, meaning he's missed opportunities to play at any level on some weekends.

Like Anderson, Jarrad Waite won't be risked after the veteran forward voluntarily pulled out of the Brisbane encounter just minutes before the opening bounce. Rookie Tom Murphy replaced the 35-year-old in the side and retains his spot for another week and a second career game at senior level.

Meanwhile another encouraging game in the VFL has resulted in Alex Morgan taking a giant step forward. The former Bomber edging ever-closer to an AFL debut; listed as an emergency. He is joined by Will Walker, Ben McKay and Ryan Clarke.
