Fremantle looks set to make wholesale changes for this weekend's clash with St Kilda at Subiaco Oval.
Chris Tarrant has been booked in for season-ending shoulder surgery, while Josh Carr and Brett Peake are no certainties to play either.
The news will come as something of a relief for the beleaguered Saints, whose finals chances are on the line after losses to Collingwood and West Coast over the past three rounds.
Experienced pair Jeff Farmer and Des Headland are chances to come in for the Dockers.
Tarrant, though, was booked in for surgery later this week, meaning the former Magpie misses the opportunity to play his 200th AFL match against Richmond in round 21 this season.
Dockers coach Mark Harvey added that rugged midfielder Carr and running defender Peake would also be assessed after injuring themselves during last weekend's four-point loss to Sydney.
Carr hurt his groin during the first half but managed to play on.
"He's (Carr) to be assessed, he'll be 50-50 at this stage, that's where's he's at," Harvey said.
Peake was also only a 60-40 chance after spraining shoulder ligaments in a courageous marking contest.
"He hurt it in that collision late in the game," Harvey said. "There was a lot of courage involved in that (but) he has got sprained ligaments, so there's nothing structurally wrong (and) he's going to be assessed as well."
The three injuries could be compounded by the loss of defender Antoni Grover, who was a late withdrawal from last week's side with personal issues, and is doubtful for this week as well.
On the flipside the Dockers coach said Headland and Farmer were ready to go.
Harvey said former Brisbane midfielder Headland had made a huge effort to play again this season after hurting his knee against Richmond in Round 4, saying that selecting him would be a good psychological reward for what he's done.
But for Farmer, returning from a one-match suspension for striking Eagle Mark Nicoski in the Round 18 Western Derby, the last three matches of the year could well determine whether the 246-game veteran remains at Fremantle next season.
Harvey refused to speculate on the uncontracted Docker's future, simply saying he had faith in the 31-year-old.
"I want to talk to him and find out if he can get better at his age," Harvey said.
"We are watching things unfold at the moment and are seeing Olympians over 30 years of age winning gold medals, so I'm not sure why our game is any different."
"James Hird won a best and fairest at 34, Crawford and Richardson are still playing great footy ... and the thing with the Wizard that is extraordinary is that he knows how to play the game like very few others do."
