North Melbourne midfielder Luke Davies-Uniacke has been withdrawn from the side ahead of its Round 7 hitout with Melbourne at the MCG, due to a heel injury.

Originally omitted, recruit Darcy Tucker has since been called upon to take the No.9's spot and will play his fifth game for the season.

Elevated into the emergencies is rookie draftee Blake Drury, marking the first time the 19-year-old has been included in the club's extended team leading into an AFL game.

Hugh Greenwood, Daniel Howe, Will Phillips and Drury are the four emergencies, with the tactical substitute to be selected an hour before the bounce on Saturday night.

Tickets for the game are still available and can be purchased here.
