Fremantle veteran David Mundy will miss Sunday's western derby after being forced to stay in the AFL's health and safety protocols, but ruckman Sean Darcy is a chance to play.
Mundy missed last week's 10-point loss to St Kilda after being forced into isolation, and the Dockers announced on Tuesday the 36-year-old would remain in the health and safety protocols for longer.
Defender Brennan Cox also entered the health and safety protocols last week, but the Dockers didn't give an update on his availability.
Darcy injured his right ankle against the Saints and is listed as a test to take on West Coast.
"Sean turned his ankle pretty sharply in the third quarter against the Saints," Fremantle's general manager of football Peter Bell said.
"There is a lot of swelling there and we will see how that progresses over the next couple of days, but there is a possibility that he will be available this week."
Skipper Nat Fyfe underwent a small procedure on his back over the weekend, but no firm timeline has been set on his return.
Last week, Fyfe predicted the procedure would rule him out for between three to six weeks.
"He is going really well, he is upbeat and positive," Bell said.
"We will give it another couple of days before he will be assessed again on when he can commence running.
"At the time of the surgery it was told to us that it would be a couple of weeks before he begins running, and then a return to train and play after that."
Forward Matt Taberner (hamstring), Nathan Wilson (shoulder) and Josh Treacy (ankle) are all a chance to return.
Fremantle veteran Michael Walters appeared to injure his wrist against the Saints, but he wasn't listed on the club's injury list on Tuesday evening.
West Coast will assess Andrew Gaff (foot) and Jackson Nelson (knee) this week, but they haven't given any word on the 12 players who were ruled out last week due to the COVID-19 protocols.
Oscar Allen (foot) and Jamie Cripps (pectoral) are still about four weeks away, with Dom Sheed set to miss another six to eight weeks.
Midfield bull Elliot Yeo could return in two weeks from a calf injury.
