Schoenmakers, who injured his knee early last season in Tasmania, has been performing well in the VFL and has earned himself a recall into the team.
Hawthorn's first pick in last year's NAB AFL Draft Billy Hartung will make his debut in the Brown and Gold after being named on the bench for Saturday's match.
Jonathan Simpkin has been omitted from the team that defeated the Tigers last week, joining Will Langford (back) on the sidelines.
