Both Fremantle and Carlton have both made a late change ahead of their twilight clash at Optus Stadium.
Blues ruckman Matthew Kreuzer has pulled out of the contest due to an elevated heart rate and has been replaced by midfielder Nick Graham.
Carlton have confirmed that Kreuzer will not play again in 2018.
Dockers rookie Bailey Banfield has come out of the Dockers lineup, with forward Shane Kersten coming in.
