IN: Colvin, Fitzsimon

OUT: Gillard (omitted), Parry (omitted)

MELBOURNE has strengthened its line-up for a must-win clash with the Dockers, as it heads to Perth for a Saturday night battle at Optus Stadium.

With the playing list in good health, the Demons had plenty of options at the selection table, adding Gabby Colvin and Megan Fitzsimon to their side.

Tahlia Gillard and Jackie Parry were the unlucky duo to make way this week, as the club prepares for a hostile environment in the second last game of the home and away season.

The battle between second and third on the AFLW ladder could prove pivotal in deciding which club earns a top-two finish, and ultimately a home Preliminary Final.
