The travelling supporters celebrated wildly after the Toon took the lead against Crystal Palace in the 53rd minute with Marc Guehi's own goal.
Anthony Gordon, who poked in the low cross, led the celebrations from the Newcastle players as they darted towards the away end.
And as those in the front few rows in the visiting corner rushed forwards, one of the advertising hoardings broke and fell to the floor.
Several fans fell over with one child appearing to land on a member of security, while others scrambled to stay on their feat.
Defenders Dan Burn and Fabian Schar immediately noticed, and quickly pushed it upright and back into place with the help of security.

Their actions thankfully meant none of the travelling fans appeared to suffer any injuries.
It's the second time this season that this has happened at Selhurst Park.
Exactly the same thing happened in August when West Ham travelled to Palace.
The Hammers won the game 2-0 thanks to goals from Tomas Soucek and Jarrod Bowen, with both goalscorers helping to save a ball boy from being crushed by the boards that fell as fans celebrated Bowen's strike.

Fortunately this time there were no boy boys or girls station around that section of the sidelines, with the boards just falling to the floor.
Wild celebrations from Newcastle saw visiting fans surge out of their seats, over the seating area and into the hoardings, with questions asked about stadium security and safety.
It was the home fans who were left celebrating at the end of the game, though, as Daniel Munoz rescued a point for Palace in stoppage-time.
The Colombian full-back rose highest in the box to head in at the back post from a Guehi cross, who made amends from his earlier OG, with five minutes of added time on the clock.
The draw sees Newcastle sit tenth in the table, while it was enough to help Palace out of the bottom-three as they now sit in 17th having collected just one win so far this season.
