Forward Tom Cochrane is nearing a return to football after suffering a pre-season hamstring injury.
Cochrane is expected to train fully for the coming fortnight to determine his availability for next weekend.
Lachie Jones was cleared of any muscle injury after experiencing hamstring tightness last week, with the defender to be available this week.
Harrison Ramm underwent a successful syndesmosis repair on Wednesday and has begun his rehab, with a return timeline of five to six weeks for the young key defender.
Captain Connor Rozee will consult a surgeon in the coming days after suffering a hamstring tendon rupture on Sunday, while scans on Monday confirmed a sprained ankle and heel bruising for Miles Bergman, who has been ruled out of Round 3.
Mani Liddy is continuing to manage a groin concern, while Jacob Moss has entered concussion protocols and won't be available for selection this weekend.
Port Adelaide will name its final team for Sunday's game on Friday at 4:30pm and the Magpies will open their SANFL season on Saturday afternoon at Alberton Oval.
