UPDATE: Geelong forward Paul Chapman has been added to a long list of outs for the Cats in a further advantage to West Coast's pursuit of a top-four finish tonight at Patersons Stadium.
The Cats will now be without four of their first-choice players after Chapman failed a late fitness test because of a calf injury. The visitors have yet to name his replacement.
Yesterday, the Cats left James Kelly (groin), Josh Hunt (quad) and Billie Smedts (calf) in Victoria as they flew west fresh from an emotion-charged win over arch rivals Hawthorn.
It is understood James Podsiadly caught a late flight to Perth and is likely to play.
The Eagles strengthened their line-up significantly by including captain Darren Glass and experienced midfielder Andrew Embley.
Embley, 31, was named on the interchange bench but could start at the opening bounce despite being billed as a potential substitute in his first appearance since dislocating his left shoulder in round two.
Glass returns from suspension and Jacob Brennan has been recalled.
Sam Butler (calf) and Brad Sheppard (ankle) were forced omissions, with Mitch Brown again axed.
The Cats named inexperienced trio Jonathan Simpkin, Cameron Guthrie and Jordan Murdoch as their inclusions for a game between the sides in fifth and sixth spot.
The loser's top-four ambitions will be effectively over with just three rounds left. Geelong coach Chris Scott last night remained confident that Podsiadly and Chapman would play, stressing they were catching a later flight to Perth.
Chapman kicked three goals in the first quarter against Hawthorn last Friday night but his impact was limited after copping a heavy hit from enforcer Brent Guerra during the second term.
The Cats were disappointed to lose in-form midfielder Kelly, who, along with Hunt, was expected to miss just one game.
"He was sore to the point that we just couldn't be convinced that it was good for the long term for him to play," Scott said.
"He has been in pretty good form for the last couple of weeks so that will hurt a little bit.
"But we will bring in a couple of young guys and expect them to step up."
Smedts complained of calf soreness at a training session yesterday morning.
Embley has steadily built up game time during two appearances for WAFL club Swan Districts.
The West Coast veteran is expected to be given a one-year contract extension, provided he can safely negotiate the remainder of the season without any further major injury setbacks.
The 2006 Norm Smith medallist told The West Australian a fortnight ago he was not ready to retire, with his time out this year refuelling his passion for the game. Informal discussions have been held about his contract situation.
Embley's manager Anthony Van Der Wielen said formal negotiations would take place when his client had worked his way back into the team.
"All indications are that both parties are happy to go around again next year," Van Der Wielen said.
"First of all, Andrew just wants to get back to playing footy and to concentrate on finishing the 2012 season off.
"We'll talk about that issue more formally at the end of the season."
West Coast yesterday transferred Mark Nicoski to their long-term injury list but did not nominate a replacement.
