Fremantle captain Nathan Fyfe is recovering well from concussion and has returned to light running in the early stages of his mandatory 12-day period on the sidelines.
 
Fyfe is this week subject to the AFL's concussion protocols and ruled out of Sunday's clash against Carlton after a heavy hit against Greater Western Sydney in Sunday's 31-point win.
 
The dual Brownlow medallist completed a light running session on Thursday, both on his own and with a trainer for a short period, before leaving the track during ball movement drills. 
 
"The whole week he has looked really good. He'll take it really carefully," teammate Brennan Cox said.

Strong progress in his recovery this week could see Fyfe return against Hawthorn in round four if he passes all testing during his mandatory period on the sidelines.

Star forward Michael Walters is set to replace Fyfe in attack for Sunday's clash against Carlton and trained with the main group on Thursday after recovering from a hamstring injury.
 
Rookie forward Josh Treacy is also in the selection frame after serving his WAFL suspension.
 
Forward/ruck Rory Lobb is out of his knee brace and completed lateral movement work with a trainer away from the main group as he eyes a return in the next month.

Cox said Fremantle were wary of Carlton after the Blues' 0-2 start to the season and they would be prepared for a fit and firing Patrick Cripps. 
 
"They get criticised and that's what fuels the fire and then they come out and throw it all at us," the defender said.
 
"But we'll be ready for it and can't wait for it.
 
"I expect them to come out firing, especially with 'Crippsy' as well.
 
"They'll come out and play their brand and I think they'll come out and really give it to us in the first quarter."

Cox good to go for 50th
