Fremantle defender Luke Ryan has flagged he "definitely will be" ready to face Carlton on Saturday after battling the flu earlier this week.

Ryan's prospects of lining up for the Dockers in the third verse fifth clash was under some duress after missing training, with the All-Australian backman left feeling "sick and sorry".

The 26-year-old will be on the flight to Melbourne on Thursday however, having recovered from his recent bout of illness. Speaking to 6PR, Ryan said that he "should'd be fine" to face the Blues.

"I've turned a corner really," Ryan said of his health.

"I was pretty sick and sore on Sunday, Monday, Tuesday, but I've turned a corner lucky enough.

"I ran some laps yesterday and I'll probably do a bit more today and see how I go. Then onto the captain's run, the day before the game, I should be fine."

When questioned if he'll be lining up at Marvel Stadium this weekend, Ryan gave a prompt response.

"[I] definitely will be," he said.

The defender's place down back for Justin Longmjuir will be integral as the Dockers look to tussle with Carlton's twin towers of Harry McKay and Charlie Curnow.

Longmuir will take a near-fully fit backline to Victoria, but concerns have been raised in regards to their attacking tandem.

Key forward Matt Taberner is no certainty to face the Blues, but is understood to be on the flight to Melbourne, along with fringe youngster Liam Henry.

Back spasms and hamstring issues have hindered Taberner's campaign, while Longmuir will be without small forward Sam Switkowski and potentially veteran Michael Walters.

The Dockers will welcome back livewire Michael Frederick from a club-imposed suspension for Saturday's clash at Marvel Stadium against Carlton.
