KEY forward Jay Schulz will return for Port Adelaide's match against the Hawks at Etihad Stadium on Friday night.
Schulz was a late withdrawal from the Power's Round 20 win against GWS Giants with a back complaint.
The 30-year-old has kicked 37 goals from 18 matches this season.
Schulz replaces key defender Jackson Trengove, who has been ruled out for the remainder of 2015 with a shoulder injury.
Ruckman and vice-captain Matthew Lobbe has been named as one of three emergencies, after being omitted from the senior side ahead of Round 20.
