Jackson has put himself in frame to return from a hamstring injury after training strongly on Tuesday, Dockers coach Justin Longmuir says.
The ruckman has not played since Fremantle's round-four win over the Western Bulldogs.
"He has to get through training, but we're pretty positive about his progression and pretty positive about the work he's done," Longmuir said.
"I felt like he could have played last week. That's only my feeling, so we're hopeful."
The Dockers have moved in and out of the top eight since Jackson last played after inconsistent results against Richmond, Melbourne and Adelaide.
He will be a welcome addition alongside fellow ruck Sean Darcy for Friday's clash at Marvel Stadium, with Fremantle (4-3) sitting ninth following their most recent 18-point win over the Crows.
Jackson was probably the side's most in-form player before his injury, Longmuir said.
"We probably see Sean as our No.1 ruckman. We'll give more time to Jacko than maybe what we have in the past though and Sean will have to tidy up his forward craft at times," the coach said.
"It probably gives us flexibility to use Jacko in other places as well.
"It's always a horses for courses type mentality with how much time each of them rucks and plays other roles."
