JAMIE Elliott has continued his hot form with four goals as the Collingwood juggernaut rolled on in a comfortable 46-point win over Fremantle.

The Magpies' scintillating brand was on full show during a 10-goal second quarter, which laid the platform for the 18.5 (113) to 10.7 (67) triumph at the MCG on Saturday.

MAGPIES v DOCKERS Full match coverage and stats

The result kept Collingwood (15-2) on top of the ladder and has all but ended the faint finals hopes of Fremantle (7-10).

Adding to the Dockers' woes, they lost No.1 ruckman Sean Darcy (ankle) and young defender Brandon Walker (knee) to injuries during the third quarter.

Taylor Adams (23 disposals, seven clearances, two goals) and Darcy Moore (19 touches, 11 intercepts) were Collingwood's most influential players when the game was up for grabs early, but the premiership favourite had a raft of contributors.

Brownlow Medal fancy Nick Daicos (36 disposals, seven clearances, one goal) was busy, as was brother Josh Daicos (31, seven, one), while Jordan De Goey celebrated his 150th game in style with 26 touches.

Ash Johnson (three), Dan McStay and Adams (two each) joined Elliott as multiple goalkickers as the Magpies racked up a triple-figure score for the seventh time this season.

Moore had five intercept marks in the first quarter alone.

Jaeger O'Meara (30 disposals, 10 clearances) and Andrew Brayshaw (30, seven) fought hard for the Dockers, young midfielder Neil Erasmus (26, five) showed glimpses and Josh Treacy kicked three goals.

There were ominous signs when Collingwood kicked the first three goals of the match but Fremantle was otherwise competitive early in the contest.

It won clearances (16-6) and inside 50s (16-10) in the opening term, with Brayshaw at the heart of its midfield ascendancy, and trailed by just five points early in the second before Collingwood flicked the switch.

The Magpies kicked eight consecutive goals in less than 23 minutes to break the game wide open and piled on 10.1 to 2.1 for the second quarter, leaving the visitors shell-shocked.

Such was Collingwood's dominance, it was able to rest veteran midfielder Scott Pendlebury by substituting him out for Tom Mitchell early in the third quarter.

Dockers star Darcy hobbled off during the third term and play was held up for several minutes after Walker landed awkwardly in a marking contest.

The 20-year-old looked in extreme pain before being taken off the field on a stretcher.

Collingwood was a commanding 47-point leader at that stage and the break in play took even more sting out of the contest.

Pies' luxurious substitution
With Tom Mitchell managed and named the Magpies' substitute, the midfielder got his chance early in the third quarter, replacing 35-year-old Scott Pendlebury. Pendlebury had 14 disposals and kicked a goal to help set up Collingwood's win before the Magpies took their chance to also give him a rest, introducing Mitchell. Mitchell had 14 touches, seven tackles and six clearances, having played 44 per cent of the game.

Dockers' blows continue
With their finals hopes already fading fast, Fremantle was dealt another pair of injury setbacks. Sean Darcy (ankle) and Brandon Walker (knee) both didn't finish the game. That added to the five forced changes coming into this game, including Caleb Serong's suspension, as Freo's woes continued.

Milestone moment for Rosebury
It was a special day at the MCG for Brett Rosebury as he became just the second person to umpire 500 VFL/AFL games. After a career littered with special moments, including nine Grand Finals, this round 18 clash was a little more straightforward for Rosebury, who received a guard of honour from both teams after the game.
