Follow our Dockers v Eagles live chat

Fremantle and West Coast crank up their pre-season work to a new level when they meet in a NAB Challenge derby at Arena Joondalup this afternoon (4.10pm).

In what will be Adam Simpson's first taste of a western derby, the Eagles coach acknowledges "it could get messy" as he works a match day with his players and coaching staff for the first time.

Dockers assistant Peter Sumich will take charge of the team against the man who pipped him for the Eagles coaching role last September.

Xavier Ellis and Elliot Yeo make their first appearances for the Eagles, while the Dockers have replaced Clancee Pearce (corked leg) with draftee Brady Grey.

The West Australian chief football writer Mark Duffield and fellow AFL reporters Dale Miller and Bridget Lacy will keep you up to speed with the action as we open our live chat at 4pm
