Geelong will unveil its fifth debutant for AFLW Season 7 when it takes on Collingwood in the Djilang Match at GMHBA Stadium on Saturday.

Young ruck Kalani Scoullar has been named to make her debut, joining forces with Liv Fuller in the undefeated Cats line-up.

The move will allow fellow tall Kate Darby to concentrate her efforts in the forward line, with Mia Skinner set to miss with knee soreness.

Scoullar was elevated to the Cats' primary list on the eve of their pre-season practice match against Gold Coast Suns, after Sammy Gooden and Maddy McMahon were moved to Geelong's inactive list for Season 7.

The 18-year-old Greater Western Victoria Rebels graduate has quickly settled in to life at GMHBA Stadium and was already familiar to the Geelong Women's program, having played four matches with the club's VFLW team earlier this year.

Saturday's match will also celebrate two milestones within the Cats' team, with Darby and Jackie Parry set to play their 25th league games.

First bounce is at 4.10pm AEST on Saturday. Tickets are available through Ticketmaster. For those watching at home, the game will be broadcast on Channel 7, and can be streamed through womens.afl and the official AFLW and AFL Live apps.
