Collingwood are set to unveil midfielder Brayden Sier and hand the 20-year-old his AFL debut when the Pies travel to Gold Coast to face the Suns on Saturday night.

Following Adam Treloar's injury, the Pies are a little light in the middle of the park, and will call upon Sier to make an immediate impact.

The Pies are yet to confirm Sier's inclusion, although Nathan Buckley was seen bringing the players together at training on Thursday morning, before the playing group let out a big roar and all gathered around Sier.

Last weekend, Sier recorded 28 disposals and nine tackles in the Pies' VFL loss to the Northern Blues.
