Collingwood and a wasteful Hawthorn have fought out the first draw of the AFL season, with Hawk Dylan Moore kicking the equaliser after the siren, in an extraordinary thriller at the MCG.
Hawthorn consistently threatened to rip the game away but Collingwood's remarkable efficiency proved the difference for much of the night - until the final moments.
With Collingwood up by six points, returning skipper Darcy Moore dropped a mark he should have taken, then gave away a free kick on Dylan Moore and the Hawk kicked truly after the siren to snatch a 15.3 (93) to 13.15 (93) draw.
Hawthorn and coach Sam Mitchell will feel they let one get away after dominating inside-50s 49-25 and clearances 39-23, but going seven games unbeaten still moves them two points clear of Sydney and Fremantle at the top of the ladder.
Craig McRae's Magpies kicked a goal from a remarkable 44 per cent of their inside 50s, compared to the Hawks' 21 per cent.
Collingwood were without injured Beau McCreery and Tim Membrey and managed veterans Scott Pendlebury and Jeremy Howe.
They lost Harry Perryman to a hamstring injury in the second quarter, while Darcy Cameron battled through an apparent ankle issue.
Dan Houston (32 disposals) was superb along with Brayden Maynard (23 disposals) while on return from injury, Darcy Moore kept Jack Gunston goalless.
Jamie Elliott kicked three goals, Jordan De Goey (two goals) was dynamic and Nick Daicos (34 disposals) had plenty of the ball.
Hawthorn co-captain Jai Newcombe (28 disposals) led from the front, while Nick Watson (two goals) and Connor Macdonald (28 disposals, three goals) were influential and Karl Amon (30 disposals) and Jarman Impey (27 disposals) were busy.
The Hawks squandered chance after chance in the opening term, while Collingwood were ruthless and jagged five goals.
The Pies threatened to break away when Maynard let fly at the start of the second term to deliver to a game-high 23-point lead.
Jack Ginnivan gave Hawthorn a foothold with a terrific long-range set shot and they managed to cut the halftime deficit to five points.
Collingwood kept the Hawks at bay until Macdonald gathered, spun out of traffic and snapped a terrific goal to put Hawthorn in front for the first time - up by two at three-quarter time.
Elliott kicked two majors to restore a seven-point lead before Macdonald's third cut the lead to a point.
Steele Sidebottom nudged the Magpies out to a late seven-point lead after Cam Mackenzie was contentiously penalised 50 metres for infringing on the 'stand' rule.
But the Hawks kept pressing and Massimo D'Ambrosio snapped a point before the Moore-on-Moore late drama unfolded.
Hawthorn travel to face Fremantle next Thursday while Collingwood face Geelong next Saturday.
