It is the nightmare Knicks scenario.

It was also only a false alarm.

Twitter user @NewLookKnicks caused chaos after catching ESPN rehearse the great Zion Williamson reveal Tuesday afternoon at the Hilton Chicago.

The faux results in this run-through saw the pingpong balls bounce in the Phoenix Suns’ favor and the Knicks fall all the way to fifth — the lowest they could fall. The Knicks, Suns and Cleveland Cavaliers all have a 14 percent chance of winning the No. 1 pick with Zion’s name all over it.

This, though, was just practice, for the actual drawing takes place 45 minutes before the nationally televised NBA draft lottery, slated for 8:30 p.m. ET on ESPN.

“Once you find out what the results are — it’s so important to what it means to a franchise — that they’re dying for everyone else to know,” NBA’s executive VP Kiki VanDeWeghe told The Post’s Marc Berman earlier this week. 

“Hopefully this isn’t a sign of what’s to come,” wrote @NewLookKnicks, before panic ensued.

Knicks fans can only pray.
