Fyfe hasn't featured since Round 19 due to a hamstring injury, but is now set to return to the side on the eve of finals as Fremantle look to secure a top four spot in the last round of the season.
Lobb looks likely to miss the clash against his former side as he continues to deal with a shoulder issue that saw him spend time on the bench last weekend, despite coach Justin Longmuir being hopeful the 29-year-old would be right to go.
Lobb didn't train with the main group, instead running laps as his team readies for their trip to Canberra.
Lock it in. Nat Fyfe will make his return against @GWSGIANTS this Saturday.
Griffin Logue is in doubt, but @freodockers remain hopeful he'll get up.
Logue is dealing with an adductor/groin issue, but its not serious. @7NewsPerth

Meanwhile, Logue failed to see out the training session, leaving the track early as he dealt with a leg complaint. The valuable swingman has played 18 games for Fremantle this season, spending time up forward to compliment Lobb.
The Dockers currently sit in sixth position with 14 wins to their name for the season, still vying for a top four spot.
Fremantle will head to the nation's capital to take on GWS on Saturday. The first bounce is set for 1:45pm AEST.
