FIRED-UP Fremantle coach Ross Lyon angrily defended Zac Dawson as his Dockers threw the AFL premiership race wide open.

While many had Hawthorn and Geelong pencilled in for the flag decider, the physical and well-drilled Dockers thumbed their nose at convention, inflicting just the Cats' second loss in 45 matches over six years at their home ground.

The stunning 15-point win wound Fremantle into a $4 second favourite for the flag by pitching the arch rival Hawks and Cats into the same half of the draw and giving the WA team its first home preliminary final.

Dockers stun cats in boilover

But while Lyon urged his team to "stay incredibly focused", he bristled at suggestions he'd charged Dawson - and others - with the task to intimidate the Cats physically.

Dawson gave away a free-kick and was booked for a clash with Geelong forward James Podsiadly before the opening siren.

The pair jostled several times during the match and the former Saint was also involved in a clash with Geelong skipper Joel Selwood that could come under scrutiny.

But Lyon stood by his full-back, saying the Cats had contributed their fair share to the physical clash.

"(That's) out of line because what I saw was some Docker players go down off the ball," he said.

"It is silly question – we played within the rules. Just go to the behind-the-goals footage and have a look, you'll see what comes out.

"I reviewed them (as) marginal free-kicks at best (with) some body work.

"I just happen to be the coach of the team. I have behind-the-goal vision, I have broadcast vision that I replay and I saw them and they were incredibly marginal, marginal free-kicks.

"That is OK if they get paid, but to then focus on them is really disappointing in the context of the effort we have delivered."

The Dockers will also sweat on a clash, one of several, between gun forward Chris Mayne and Geelong's Steve Johnson, who was left lying on the ground after intitial contact between the pair propelled the Cat into Geelong runner Nigel Lappin.

Lyon was "really pleased for the players that they created an opportunity" after admitting to a mistake in sending chief tagger Ryan Crowley to Mathew Stokes while Johnson threatened to tear apart the game early.

"It was a powerful response in face of a great challenge by the team. We want to be `anywhere-anytime' team and this is a significant challenge and they got it done today."

Lyon walked away from the "garbage" of the debate about playing a final in Geelong for the first time since the 19th century, and also said resting half his team in Round 23 had likely been beneficial.

"It's hard to measure, but the analogy I used is I watched Hawthorn win last night and (then) everyone espouses that they have got a week off to freshen up for a preliminary final, so in theory it is the same model," he said.

"You would not want to be doing it every week, but after 22 home-and-away rounds, it clearly helped."

Lyon said the decision to play key defender Luke McPharlin for the first time in two months after a Round 15 calf injury had been "bold and strong".

Utility Nick Suban was subbed off with an ankle injury, but was walking around without discomfort in the rooms afterwards.

Lyon said Freo had "some sore boys that had plenty of whacks ... and there was plenty of on and off ball things that will probably be looked at I would suggest".

He said big man Aaron Sandilands played his best game of an injury-cruelled season.

"I thought he was significant when he went forward ... a real threat.

"They threw some challenges at him on spread, but we're really confident we can handle that.

"A few of the things they were doing we certainly adjusted to and it was needed ... and then (he and Zac Clarke) were able to play to their strengths, rather than having their strengths taken off them and chasing around opposition ruckmen."
