DOUBT hangs over star forward Jesse Hogan and veteran ruckman Aaron Sandilands' chances of returning this season amid injury setbacks for the Fremantle big men.

Meanwhile, injury-ravaged Stephen Hill could be sidelined yet again by quad soreness in a bitter blow to the under-pressure Dockers ahead of a crunch home game against Sydney.

In an eventful media conference on Wednesday, when Ross Lyon took issue being distracted by a photographer's bright flash, the coach also dismissed talk of a return to St Kilda and announced young defender Griffin Logue and forward Cam McCarthy had re-signed.

Lyon also insisted Nat Fyfe's sore shoulder was "really good" after getting fed up by off the ball treatment copped by the superstar midfielder.

The Dockers will rely heavily on a fit and firing Fyfe to arrest a four-game losing streak against the Swans, and Lyon could deploy his skipper forward more regularly with Hogan suffering a hiccup with his sore foot this week.

The boom recruit, who arrived at the club nursing a navicular issue, was pushing to return after a month layoff with a mid-foot sprain but is facing an indefinite stretch on the sidelines.

"We were planning and expecting him to be able to get up this week," Lyon said.

"It doesn't bode well that there's been a hiccup, but it would be remiss of me to speculate really." 

Sandilands was rested from the defeat to Hawthorn in Launceston after his first game in more than a year in the Western Derby following repeat calf problems.  

But the 36-year-old has pulled up sore after a match simulation session, and his chances of playing another game in purple appear in serious jeopardy.

"If it was a calf strain, it would be significant rehabilitation and he'd have to get back late in the season," Lyon said.

"It would be at least three weeks I would imagine, if it's a strain."

Hill is not "100 per cent" to face the Swans after battling quad soreness after his comeback from a hamstring strain.

The gifted midfielder has managed only 16 of a possible 38 games since the start of last season after repeat soft-tissue dramas.

"I really feel for Stephen. I've been with him a long time. He's a pleasure, he's a top-flight player for us. It's been a really tough year-and-a-half for him," Lyon said.

The Dockers have tumbled from sixth on the ladder to 13th over the past month and Lyon's position has come under increasing pressure.

In the wake of Alan Richardson's departure from St Kilda, former Saints greats Nick Riewoldt and Nick Dal Santo have suggested Lyon would be welcome back at Moorabbin.

But the 52-year-old reaffirmed his commitment to Fremantle, where he is contracted until the end of 2020.

"At the end of the day, they're (Riewoldt and Dal Santo) in the media. Certainly, they're personal friends, they've been professional colleagues, but I'm fully committed to Fremantle," Lyon said.

"I've loved my time here. It's a tough spot, but that's what you sign up for. I don't want to indulge the conversation."

Lyon wouldn't be drawn on whether Logue, who has signed for three more years, would be recalled after being a surprise omission against the Hawks.

"He's a fine young person, great athlete, we knew his game sense was the one that was going to take time," Lyon said.

"The (Alex) Rance model was a longer model than we'd like, but it's not too dissimilar.

"We're confident with application, coaching and determination he can become a great player for us."

McCarthy has signed a one-year extension for the 2020 season.
