Saturday AFL finals as they happened: Dockers overcome 41-point hole to stun Dogs, Cats survive thriller against Pies

Fremantle are through to the semi-finals after an almighty comeback!

Justin Longmuir's side found themselves down 42-1 to start this match, and Longmuir had his head in his hands. It finishes 11. 7. (73) to 8. 12. (60) in front of an absolutely raucous Optus Stadium crowd.

But they've somehow pulled a rabbit out of the hat, stunning the Bulldogs in a second-half onslaught.

"There are wins that you can build the club around," says Alister Nicholson on commentary.

"This is a victory that no footy fan will ever forget."

Fremantle will face Collingwood next weekend in a do-or-die semi-final at the MCG.

Two goals in four minutes.

That's the equation for the Bulldogs to keep their season alive.

Massive goal from Nathan O'Driscoll from the boundary!

He trapped Josh Dunkley in the forward pocket and the umpire deemed it to be holding the ball.

But then he goes back and drills it on that wonderful left foot of his.

Dockers with a two-goal lead, just over seven minutes left. It's getting late very early for the Dogs.

UNBELIEVABLE FORWARD PRESSURE FROM MICHAEL FREDERICK!

Ed Richards was ambling out of the forward 50 like it was a Sunday stroll, but it's not Sunday yet, Edward, these are the elimination finals!

Frederick comes up behind him and mows him down and the ball bobbles to Walters who snaps through his third goal of the night.

Freo's lead out to 11 points, the crowd is absolutely delirious.

The Bulldogs are capitulating in front of our very eyes!

A brainfade from Laitham Vandermeer on the mark makes a 50m set shot one from the goal line for Griffin Logue and the Dockers have the lead!

What a performance this has been.

Fremantle leads the Inside-50 count 7-0 so far in this fourth quarter. It's been one way traffic.

Jye Amiss with ice running through his veins!

Forget his miss from earlier on in the match, he goes back and absolutely nails this set shot to kick his second of the evening and we're knotted at 53 apiece.

Fremantle absolutely running over the top of the Bulldogs now.

Luke Beveridge is looking increasingly antsy on the sideline.

Caleb Serong is the leading ball-winner on the field with 26 disposals, but he's closely followed by Andrew Brayshaw and Jack Macrae, who both have 25 each.

Both teams deadlocked on 297 disposals each, Dogs leading clearances 29-26 and Inside 50s 46-44.

Absolutely nothing in it heading into the final term.

Getting a sense of deja vu here as we have our fourth game of the weekend heading down to the wire.

Fremantle are almost all the way back, they've chipped and chipped and chipped and the Bulldogs' lead, which once stood at 41 points, is back to just five.

We often see teams expending a lot of energy getting themselves out a huge hole that they're left with no energy to actually overcome the hump.

Surely this home crowd can ride Freo home here. The Bulldogs you feel have gone into game-saving mode rather than taking the game on, which can often backfire.

Can you believe it?! The margin is back to just four points.

The score was 42-1 the Bulldogs' way, I repeat, 42-1. What an outrageous turnaround.

Lobb drills another set shot from the wrong side for a right footer, and the Dockers are absolutely up and about here.

"Lobb has really turned into a monster," says Nicholson on commentary.

It's the closest Freo has been since the two-minute mark of the first term.
