Clark was drafted by the club with pick 8 in the 2022 AFL Draft after an impressive junior campaign, serving as captain of the Geelong Falcons in the 2022 NAB League Boys season, averaging 25 touches per game.
The 18-year-old becomes the second Geelong debutant in 2023 after Cooper Whyte ran out for the first time in Round 2.
The midfielder has impressed during his time in the VFL this season, collecting 12 disposals against Southport in Round 8, following a 29 disposal and four tackle effort against Coburg the week prior.
Geelong Cats announced the news of the debutant on Wednesday, posting a clip of Clark calling his parents on social media.
