The Empire State Building, in the heart of New York City, lit up green on Sunday night to show support for the Philadelphia Eagles after the team won the NFC Championship and clinched a spot in Super Bowl LVII.

The notion that one of the most iconic buildings in the world with the New York Giants and the New York Jets playing in their backyard would light up green to support a rival didn’t sit well with some football fans.

The backlash immediately began on social media.

NYC Sanitation, whose colors are also green and white, tweeted, "For anyone who finds this as treacherous, traitorous, and unforgivable as we do - just pretend it's green and white for #NewYorksStrongest. We take out the trash every day...and next year, that'll include the Eagles."

The Eagles defeated the 49ers, 31-7, to get back to the Super Bowl, which will take place Feb. 12 at State Farm Stadium in Glendale, Arizona, and will be seen on FOX.

Philadelphia was propelled to victory behind touchdowns from Jalen Hurts, Miles Sanders and Boston Scott. All three players scored rushing touchdowns and Sanders had two of those scores.

Hurts, an NFL MVP candidate, was 15 of 25 with 121 passing yards. He also had 39 yards on the ground on 11 carries with a touchdown. Kenneth Gainwell led the Eagles in rushing yards with 48. Sanders had 42 and Scott had 21.

DeVonta Smith led the Eagles in receiving with two catches for 36 yards. A.J. Brown had four catches for 28 yards.

Things didn't get better for the social media team after the Empire State Building account tweeted that it changed its color to red to support the Kansas City Chiefs who defeated the Cincinnati Bengals to win the AFC Championship.

In the final moments, Patrick Mahomes galloped for a first down and picked up more yards after he was pushed to the ground when he was already out of bounds.

It set up a Harrison Butker go-ahead field goal.
