Justin Longmuir admits he's "not happy" with Fremantle's crippling injury list but says the responsibility of ensuring a healthy squad falls on everyone within the club's football department.
The Dockers have about one-third of their best team out of action and have lost more games to injury than any other club in Longmuir's first year as coach, except for North Melbourne.
Their key position stocks have been hit particularly hard, with Alex Pearce, Joel Hamling, Griffin Logue and Jesse Hogan all missing extended periods of the truncated 2020 campaign.
The boost felt through captain Nat Fyfe's return from a hamstring strain for Sunday's meeting with Collingwood has been offset by electric star Michael Walters going out of the side with a similar issue.
Fremantle have also confirmed this week Darcy Tucker will miss the rest of the season with a significant hamstring tear.
"We're not happy with the situation," Longmuir said.
"We're constantly reviewing everything we do as a football department, so we need to get it right.
"It's on everyone. It's on the way we prepare the and it's on the way they (players) prepare themselves.
"Some of it's unlucky. We review every injury on its merits and come to a finding on all injuries.
"We'll continue to do that and continue to work on all our practices at the footy club, individuals included."
Fremantle have used 32 players this season - only Sydney, the Bulldogs (both 35) and Adelaide (33) have used more - and have handed senior debuts to five young players.
"Clearly as a coach you'd like your best players out there and a full list to choose from, I'm not going to shy away from that," Longmuir said.
"It's frustrating, but for where we're at, it creates a lot of opportunity for players and I think this period of time is going to hold us in good stead for the future.
"We get to see what our depth is like and we get to expose Tobe Watson, Michael Frederick and those types of players earlier than we would if we had a full list."
Walters could be back for the Dockers' round 11 match against Hawthorn, after a bye in round 10.
Veteran midfielder Stephen Hill (adductor), key forward Jesse Hogan (calf), young gun Sam Sturt (ankle) and Stefan Giro (ankle) could also be available after the bye.
