The Magpies had already booted eight straight goals as they moved through a dominant second quarter against Port Adelaide at the MCG before Daicos brought the house down.
Just moments after Daicos' brother Josh slotted a major from 50 metres out, the Pies were hungry for more and looked to pounce on a loose ball on the broadcast wing.
The ball flirted with the boundary line and hugged the perimeter so closely all players stopped in the assumption that the ball had gone over the line, only for no whistle to arise.
In a state of confusion and with the ball in his hands, Magies forward Dan McStay looked to the field umpire before realising play was still alive.
"McStay saw it go across the line but the umpire didn't call it," commentator Mark Howard said on the Fox Footy broadcast.
McStay soon moved the ball forward to the younger Daicos, before veteran Scott Pendlebury would link up in the ball movement chain, flipping the Sherrin back to Daicos with an over-the-head handball as the young Magpie kept running toward his side's attacking 50.
Daicos then staved off a tackle and lined himself up from 45 metres from goal on a tough angle before spearing a shot through the middle of the two big posts at the city end.
