Fremantle will need to make at least one selection change for Saturday’s RAC Derby with captain Nat Fyfe ruled out with concussion.

Here’s who could come in for the clash.

Sean Darcy

The ruckman was managed against St Kilda and shapes as a likely return. On Tuesday, senior coach Ross Lyon said that Freo would likely go for two rucks against West Coast.

“Sean will need to jump through some hoops, but I think he’ll be available,” Lyon said.

“The way West Coast play with the big guys, it’s certainly a consideration (playing two ruckmen).”

Mitch Crowden

Racked up 32 possessions, seven clearances and seven inside 50s for Peel against West Perth on Saturday. The midfielder played nine games in his debut season and is one of the more likely Fyfe replacements.

Stefan Giro

The speedy midfielder could also come in to replace Fyfe. Collected 24 disposals and kicked a goal on the wing for Peel against West Perth. Played 10 games in his debut season.

Tom North

Yet to debut, Tom North is also a good chance to line up against West Coast. The midfielder collected 27 disposals, six clearances and 11 tackles against West Perth.

Sam Switkowski

The small forward played a full game against West Perth as he makes his return from a hamstring injury and delivered with 17 disposals, seven inside 50s and a goal.

Brett Bewley

Bewley is listed as a test to return to football this week from an ankle injury. The mature aged recruit is yet to make his debut but he may have to spend some more time at Peel before earning that call up.

Brennan Cox

Played limited minutes for Peel but still kicked two goals. May need more time before being available for selection.

Sam Sturt

The no.17 draft selection impressed against West Perth and is starting to put his hand up for a debut selection. Playing on the wing, Sturt had 20 disposals, five marks and a goal.
