Dockers coach Ross Lyon has confirmed that skipper Nat Fyfe is a certainty for round one.
Fyfe will not play in Sunday's match against the Eagles in Mandurah after elbow surgery post the AFLX competition last month.
“He will definitely play round one. If it was round one he would be playing (this weekend). We play on Sunday, the staples come out on Monday so we missed by a day,” Lyon said.
“In the end it was just risk management. He could have played all the games and got to round one but you leave yourself open to him being inflamed in round seven and then he misses a game.”
Sean Darcy and Reece Conca both trained well on Friday and are expected to play minutes in Sunday's match.
The AFL confirmed on Friday that the pre-season derby is a sell-out and no more tickets will be sold.
