Inclement conditions are expected in Perth for the contest. 

Collingwood coach Nathan Buckley this week admitted Cox’s form had been "under par" so far in 2020 and that he has become a "whipping boy" of fans.

The Pies will regain powerful forward Jordan De Goey for the important game against fellow flag hopefuls after he missed last week’s clash with Hawthorn. 

Geelong will enter the match as selected.
