Chris Mayne and Nat Fyfe are virtual certainties to face Port Adelaide on Sunday but Zac Dawson's spot in the team will have to be assessed after missing seven weeks with a knee injury.
That was the take of coach Ross Lyon on his club's playing stocks after his team went through their paces at Fremantle Oval on Wednesday.
He urged people not to expect too much of Fyfe, who comes back into the team at AAMI Stadium after 12 weeks off for major shoulder surgery.
"On Nathan, we are excited to have him back and we think he will give us an emotional lift but obviously someone will go out of the team and that is the downside to it," he said. "We have got to make sure that we don't set expectations too high.
"He has missed 12 weeks. He is certainly fit and raring to go but we just want him to come in and play a role and reintroduce himself to the business of AFL football."
Although Mayne missed last weekend's win over Greater Western Sydney with calf tightness, Lyon expected him to be an automatic selection provided he got through the club's main training session on Friday.
"I spoke to Jason Weber and he is really confident that he will come up," he said. "We are excited about that. Zac and Chris did what they had to do today and then they will train fully at the main session and make themselves available.
"Chris would be automatic and then we would have to discuss Zac with period of time out and the balance of the team."
Dawson could play his first WAFL match for Perth, who face East Perth this weekend.
Greg Broughton is also likely to be available after missing the weekend with back tightness. "He did bits and pieces as well and he would be up for selection as well," Lyon said.
Lyon again played a straight bat on speculation about the playing future of Collingwood power forward Travis Cloke, who is the subject of a five year $5 million offer from Fremantle. The Magpies, tired of conjecture regarding Cloke's contract and concerned about his dipping form, have put talks on the contract on hold until the end of the season.
"What Coillingwood do with their players is irrelevant to me as coach of the Fremantle Football Club," he said.
"Clearly Chris Bond and Brad Lloyd have a strategy and they are going about their business but there has been a lot of talk about Travis Cloke and nothing I can add to."
