A desperate Port Adelaide has survived a stirring Collingwood fightback to keep its top-four hopes alive.

The Magpies booted four straight goals in the third term to narrow the deficit to eight points, before the Power responded on their way to a 14.14 (98) to 10.11 (71) victory at Adelaide Oval on Sunday night.

The 27-point win leaves the Power sixth on the ladder, trailing Sydney on percentage and within one game of fourth-placed Richmond.

For the Magpies (8-1-11), they are now officially out of finals calculations after their first loss in more than a month.

The Power appeared to have the game in their keeping with a handy 34-point lead at the 10-minute mark of the third quarter before the Magpies found another gear.

Swingman Ben Reid booted two quick goals either side of Will Hoskin-Elliott's brilliant snap from the pocket.

And when Steele Sidebottom turned and goaled, the Magpies had kicked four goals on the trot and had all the momentum.

But a couple of key plays from Power spearhead Charlie Dixon, some Robbie Gray magic and a captain's goal from Travis Boak ensured the home side got over the line.

An undermanned Magpies side, playing without suspended ruckman Brodie Grundy and injured midfield trio Scott Pendlebury, Daniel Wells and Levi Greenwood, gave everything they had.

The Power over-used the ball early in the game, with 62 handballs and 48 kicks in the first quarter as they attempted to play on at all costs.

But more alarming was the fact they laid just two tackles compared to Collingwood's 19.

The intensity lifted in the second term, with the Power hunting in packs, forcing turnovers and capitalising on the scoreboard, winning the tackle count 20-19 in the quarter.

The Power kicked five goals to three in the term to lead by 22 points at the main change.

Gray had the yips with his set-shot goal-kicking, but was dangerous in attack.

He produced a brilliant goal from the pocket after a great bit of ruck work from Patrick Ryder, reminiscent of their match-winning tandem against St Kilda earlier in the season.

As expected, Ryder was dominant in the absence of Grundy, but Mason Cox competed strongly and took several contested marks.

Dougal Howard was a surprising choice in defence in his first senior game since tearing his ACL last year, but did a solid job on Darcy Moore and drifted forward to boot the last goal of the game.

Power vice-captain Ollie Wines may have a case to answer with the Match Review Panel for a hit on Tom Langdon in the first quarter.
