North small defender Marley Williams could be an important inclusion as the Roos prepare to tackle the Power on Saturday.

Williams has missed the past two matches with a back injury and will face a fitness to test later this week to ascertain his availability.

It’s a similar set of circumstances for Jarrad Waite and Mason Wood who missed with calf injuries.

After sitting out last weekend’s VFL match, Sam Wright is due to continue his comeback from an ankle and foot injury this week.

The highly valued defender was a late withdrawal from the Werribee side that defeated Coburg last weekend.

Ruckman Braydon Preuss will undergo a fitness test after injuring his back in the match.
