Fremantle will use the pre-finals bye to build star midfielder Hayden Young's fitness with the aim of increasing his game time in a cutthroat elimination final at Optus Stadium next week.
Young has played eight games this season due largely to repeat hamstring injuries, and he returned from a groin setback against the Western Bulldogs last Sunday to play a crucial midfield role.
"The medicos and fitness guys handled his game time really well ... and I thought he had a big impact on the game," Dockers coach Justin Longmuir said.
"He's been disappointed when he's had those repeat injuries, but he just got back to work and worked his backside off. That allows him to come in and have a big game against a really good midfield."
