Knicks fans were left outraged on Thursday as City Hall made a bizarre mistake ahead of the team’s championship parade.

Each member of the New York roster had their jersey hung from City Hall — including Dillon Jones, who made just seven appearances for the team this season after signing on a two-way deal in January.

But as The Post’s Jared Schwartz captured, Jones’ uniform number was displayed as No. 33, the retired number of the great Patrick Ewing.

Jones wore No. 1 in his appearances for the Knicks, and No. 2 for the G League Westchester Knicks, but the confusion appears to come from the fact that he’s listed as No. 33 on the Knicks’ roster.

Jones previously wore the number for the Wizards in last year’s preseason before being cut by the team.

Nonetheless, fans were shocked by the mistake.

“Epitome of Knicks parade fail,” one wrote on X.

“TAKE IT DOWN NOW!!!!,” another said.

And a third claimed: “someone’s getting fired.”

While Ewing last suited up for the Knicks in 2000, he was ever-present during the team’s championship run this year, and was in San Antonio as the team clinched the Finals on Saturday in Game 5.

The legendary big man celebrated the team’s first title in 53 years as he held the Larry O’Brien trophy alongside Jalen and Rick Brunson.

Jones, meanwhile, did not suit up during the playoff run, and last saw the court for the Knicks back on April 12 in the regular season.

The 2024 first-round pick also earned a ring with the Oklahoma City Thunder last year, for whom he made 10 appearances for in the postseason.
