Collingwood has been forced to make two changes to its team for Saturday night’s game against Gold Coast at Metricon Stadium.

Adam Treloar (hamstring) and Levi Greenwood (concussion) have been ruled out, with the pair replaced by emerging players Brayden Sier and Ben Crocker.

Sier, 20, will make his AFL debut after showing great form in the VFL in recent weeks.

Crocker is back in the AFL team for the first time since the loss to Geelong in round eight.

He kicked five of Collingwood’s 10 goals in the narrow VFL loss to the Northern Blues at the Holden Centre last weekend.
