Jase Burgoyne has been ruled out of this weekend's game with a lower leg injury from Sunday's Geelong clash.
The 22-year-old sustained a partial tear of the plantaris tendon, with a timeline for return to become clearer in the coming days.
Ivan Soldo has entered concussion protocols, suffering delayed symptoms following a head knock in Saturday's SANFL match.
Jack Lukosius will be assessed this week and is expected to rejoin full training on Wednesday, while Jacob Moss is also a test as he prepares to return from a broken ankle.
Miles Bergman's shoulder surgery last week was a success, with the midfielder recovering well and beginning the early phases of rehab.
Port Adelaide will name its team for the Fremantle game on Thursday at 5:50pm ACST.
