Forward line trio Matt Taberner, Michael Walters and Sam Switkowski are all potential ins for Fremantle’s clash with Collingwood on Sunday at Optus Stadium.

The trio have come into the extended squad alongside Brandon Walker, who played as a medical sub against Gold Coast in round nine, and ruckman Lloyd Meek.

Key forward Josh Treacy is the only out at this stage, with the final 22 to be confirmed on Friday afternoon on fremantlefc.com.au.

Collingwood have made seven inclusions to their squad in Mason Cox, Jamie Elliott, Scott Pendlebury, Jack Ginnivan, Nathan Murphy, Reef McInnes, Trey Ruscoe.

Aiden Begg (omitted), Finlay Macrae, (omitted), Callum Brown (omitted) and Jack Madgen (shoulder) are out at this stage.

Walters has been training alone this week on a treadmill in a bid to play in the jumper he designed for Sir Doug Nicholls Round.

He emerged from isolation on Thursday afternoon to train away from the group.

“We’ll see how he pulls up, he’ll be touch and go,” Senior Coach Justin Longmuir said about Walters on Thursday.

“We’re not going to take any risks unless he’s 100 per cent. 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.”

Both Matt Taberner (hamstring) and Sam Switkowski (concussion) trained on Thursday as they look to return from 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.”

Bouncedown for the clash is at 3.20pm, with the game broadcast live on Channel 7, Fox Footy and streamed on Kayo.
