The Fremantle forward line could receive a boost against Collingwood on Sunday, with Michael Walters, Matt Taberner and Sam Switkowski all pushing to be available for selection according to senior coach Justin Longmuir.

Taberner and Switkowski will be in action at Thursday’s main training while Walters will train separately when he exits the Health and Safety Protocols later on Thursday.

Longmuir said Walters would need to show he is at full fitness after spending a week in isolation. If fit, he will run out with his teammates in the Indigenous Jumper he designed for the 2022 season.

“Sonny comes out of health and safety protocols later today, he’ll get a session in and we’ll see how he pulls up, he’ll be touch and go,” Longmuir said.

“We’re not going to take any risks unless he’s 100 per cent. It’s such an individual case by case situation.

“He’s got a treadmill at home and by all reports he’s been training well and pulling up well, so today won’t be his first run - but we still need to see if he pulls up well from today. We’ll have to play it by ear.”

Switkowski is a test after sustaining a concussion in round eight while Taberner is looking to return after missing three weeks with a hamstring injury.

“Tabs needs to get through full training to put his hand up, we’re confident he’ll do that, but until he does we won’t have clarity,” Longmuir said.

“We expect Sam to do full training today and play.”

Longmuir acknowledged that Fremantle would have benefited from having a player like Switkowski in their round nine loss to Gold Coast in the wet.

Fremantle won the inside 50s 65 to 36 but were convincingly beaten by six goals.

“He’s become a really important player,” Longmuir said.

“He’s well regarded in his ability to pressure and harass the opposition but I’m really starting to see the offensive side of his game come out. He shows really good composure in those contested ball situations for us to be able to move the ball from inside to out.

“He’s a really good forward 50 stoppage player. I think we had 26 forward 50 stoppages and we didn’t make much of them. He would have really thrived under those conditions.

“We missed him, he’s recovered well from his concussion and hopefully, we’ll see him back this week.”

Longmuir added that defender Alex Pearce was managing soreness in his ankle.

"He's given that ankle another tweak, we’ll expect him to put his hand up to play but we’ll see how he goes today. He’ll have to tick a fair few boxes before we get there," Longmuir said.

"If we thought it would be of benefit to have a week off, we’d consider it but that’s not what the doctors are saying.

"It’s just soreness and something he’ll have to manage. It’s not related to previous injuries, he’ll just have to manage it through the year."

While Nat Fyfe won’t play against Collingwood, Longmuir said the captain would receive some vital 18 on 18 match simulation at training on Thursday as he builds his game fitness.

“He’s going to ramp up his training today in full team training, he’ll join in on 18 on 18. We’ll see how he gets through the first couple of weeks of full training to see what the best plan is for him,” Longmuir said.

“He’s doing everything he can to be a part of it, he wants to get back and lead by example on the field and do what he can to move the team forward.”
