Friday, October 16

FIRST PRELIMINARY FINAL

Port Adelaide v Richmond, Adelaide Oval, 7.20pm ACST (7.50pm AEDT)

PORT ADELAIDE

B: Darcy Byrne-Jones, Tom Jonas, Trent McKenzie
HB:
Ryan Burton, Tom Clurey, Hamish Hartlett
C:
Karl Amon, Tom Rockliff, Xavier Duursma
HF:
Brad Ebert, Todd Marshall, Connor Rozee
F:
Zak Butters, Charlie Dixon, Robbie Gray
FOLL:
Scott Lycett, Ollie Wines, Travis Boak
I/C:
Sam Powell-Pepper, Dan Houston, Steven Motlop, Peter Ladhams
EMG:
Riley Bonner, Jarrod Lienert, Boyd Woodcock, Justin Westhoff

No change

UNAVAILABLE: Nil

NOTES: This is the scenario Ken Hinkley must have dreamed about, with a fully fit list to pick from heading into a home preliminary final. Duursma (concussion) and Marshall (shoulder) are both likely to play, despite spending the bye week on modified duties at training, while young forward Mitch Georgiades (hamstring) has also recovered. Given there are no fitness concerns, expect Port Adelaide to go into the preliminary final against Richmond unchanged from the team that defeated Geelong in the qualifying final a fortnight ago.

RICHMOND

B: Dylan Grimes, David Astbury, Noah Balta
HB: Bachar Houli, Nick Vlastuin, Jayden Short
C: Kamdyn McIntosh, Jack Graham, Marlion Pickett
HF: Shai Bolton, Tom Lynch, Dustin Martin
F: Jason Castagna, Jack Riewoldt, Daniel Rioli
Foll: Toby Nankervis, Trent Cotchin, Shane Edwards
I/C: Liam Baker, Dion Prestia, Kane Lambert, Nathan Broad
Emerg: Josh Caddy, Mabior Chol, Oleg Markov, Jake Aarts

No change

UNAVAILABLE: Ivan Soldo (knee), Sydney Stack (suspension), Callum Coleman-Jones (suspension)

NOTES: The side was a lot better balanced against St Kilda after the inclusions of Lynch and Broad, with the latter allowing Astbury and Balta to chop-out in the ruck when required. Without genuine seconds footy, it's difficult to see any players outside of the 22 forcing their way into a semi-final-winning side. A proven finals performer in Caddy waits in the wings if injury strikes a midfielder or forward. - Sarah Black

SECOND PRELIMINARY FINAL

Brisbane v Geelong, Gabba, 6.40pm AEST (7.40pm AEDT)

BRISBANE

B: Ryan Lester, Harris Andrews, Brandon Starcevich
HB: Grant Birchall, Darcy Gardiner, Daniel Rich
C: Mitch Robinson, Jarrod Berry, Hugh McCluggage
HF: Cam Rayner, Dan McStay, Dayne Zorko
F: Charlie Cameron, Eric Hipwood, Oscar McInerney
Foll: Stefan Martin, Lachie Neale, Jarryd Lyons
I/C: Callum Ah Chee, Zac Bailey, Lincoln McCarthy, Keidean Coleman
Emerg: Noah Answerth, Cam Ellis-Yolmen, Jack Payne, Archie Smith 

No change

UNAVAILABLE: Marcus Adams (foot)

NOTES: One headache looms for Brisbane with the likely availability of Answerth who has almost fully recovered from a groin problem that kept him out of the qualifying final. The Lions managed to stifle the Richmond small forwards without him and will have their hands full with Gary Ablett, Luke Dahlhaus and Gryan Miers. Some thought might be given to bringing Ellis-Yolmen in to match the bigger Geelong midfielders, but coach Chris Fagan has a history of sticking with winning teams. - Michael Whiting

GEELONG 

B: Jed Bews, Lachie Henderson, Jake Kolodjashnij
HB: Tom Stewart, Harry Taylor, Mark O'Connor
C: Zach Tuohy, Joel Selwood, Sam Menegola
HF: Luke Dahlhaus, Tom Hawkins, Gryan Miers
F: Gary Ablett, Patrick Dangerfield, Gary Rohan
Foll: Rhys Stanley, Cam Guthrie, Mitch Duncan
I/C: Mark Blicavs, Brandan Parfitt, Jack Henry, Sam Simpson
Emerg: Esava Ratugolea, Tom Atkins, Brad Close, Zach Guthrie

No change

UNAVAILABLE: Jack Steven (hamstring)

NOTES: How do you drop anyone from that semi-final performance? Simpson was impressive in his first game since a hamstring strain in August and should hold his spot over Atkins and Close. Stanley jarred his knee in the latter stages against the Pies but isn't expected to be any concern to tackle the Lions. The consideration to play Ratugolea remains but the Cats' front half has stacked up without him. - Mitch Cleary
