Fremantle captain Nat Fyfe is guaranteed to make the trip to Launceston to face Hawthorn, according to senior coach Ross Lyon.

Fyfe appeared to hurt his shoulder in a collision during Saturday’s RAC Derby and returned to the ground with his right shoulder strapped.

Lyon said that Fyfe was capable of playing through any discomfort.

“100 per cent he’ll be there. He actually feels pretty good,” Lyon said.

“He went in last week (against West Coast) a little bit sorer than we’d like, but once you’re out there, Nat doesn’t use any excuse, and we don’t.”

Lyon said that Fremantle could make at least two changes for Saturday’s clash.

Ruckman Sean Darcy is set to relieve Aaron Sandilands for the long away trip and midfielder Stephen Hill is a chance to return from a minor hamstring injury.

“Stephen Hill is a real possibility and we committed last week to Sean Darcy coming back in, he’s just freshened up,” Lyon said.

“Sean was a bit battered and he would have gotten a bit more battered on Saturday night (if he played) as (Nic) Natanui was amazing with his athleticism.

“Aaron is pretty sore but he’ll recover but that was pre-planned and we think well managed.”

Fremantle face a big test against the in-form Hawks.

While Lyon said Fremantle were ‘incredibly disappointed’ with their performance against West Coast, he also backed the team's ability to deliver against high quality opponents.

“Our body of work for the year has been incredibly strong, we’ve had some wonderful victories against Port Adelaide, Brisbane, GWS and Collingwood, who all sit in the upper echelons on the ladder,” Lyon said.

“The past three weeks have been a challenge for us, we believe in our system, there’s been some personnel challenges that we need to work through and we’re comfortable we’ll come out on top.

“We’re really keen to get down to Tasmania and have the opportunity to improve.”

Lyon said that there were some elements to build on from Freo’s loss to West Coast.

“Within that wreck of a score there’s a bit to work with, (Fremantle had) 60 (inside 50) entries, we won the ground ball but our efficiency, which has been our Achilles heel, really let us down,” Lyon said.

“For the first time in a long time we didn’t defend very well, particularly out of the middle. There are some clear areas to work on.”
