A viral and revolting incident in the stands at an NFL playoff game on Sunday has already earned one football fan a lifetime ban — and it ended up costing him his job.

The fan, identified as Ryan Caldwell, was captured on video heckling a female Packers fan — and repeatedly calling her a “dumb c**t” — while her fiance, Alexander Basara, filmed the entire altercation in the stands during Sunday’s wildcard game in Philly, an Eagles win over the Packers.

Caldwell has been banned from all future events at the Eagles’ home ground of Lincoln Financial Field, a source with knowledge of the situation confirmed to The Post, and his employer, BCT Partners — a diversity, equity, and inclusion (DEI) focused management consulting firm based in East Brunswick, New Jersey — is involved.

“The management at BCT Partners has been made aware of a video circulating involving an employee making offensive remarks outside of the workplace,” the company said in a statement released Monday on X, without naming the employee.

“BCT Partners denounces this type of behaviour, and we take this matter extremely seriously. As an organisation that has always stood for inclusivity, the conduct displayed was completely unacceptable and stands in direct opposition to our company values.

“We have already begun a full investigation as an internal personnel matter to determine what actions will be taken. We sincerely apologise to everyone affected by this behaviour and remain committed to fostering a culture of respect for all.”

Later Tuesday, BCT Partners decided to fire Caldwell.

According to internet sleuths, the fan is a project manager with the company.

BCT Partners aims “to harness the power of diversity, insights, and innovation to transform lives, accelerate equity, and create lasting change,” according to its website.

Caldwell’s LinkedIn page no longer exists and his social media accounts have been deleted.

The Eagles will take action against the heckler, according to a local report.

“Big Dom has identified the guy and woman involved in this incident,” Derrick Gunn, an Eagles podcaster, reported, referring to Dom DiSandro, the senior adviser to the general manager/chief security officer/game day coaching operations for the Eagles.

“. The guy will be banned from future Eagles games . the Eagles will be sending the woman Packers gear as an apology . Eagles once again showing what a class organisation they are.”

Basara shared the video and explained that the man’s heckling was “unprovoked” while they were simply cheering for Green Bay.

“Don’t call her a dumb c**t,” Basara told the man, who doubled down on his insults.

“She is an ugly dumb c**t,” the Eagles fan said.

The woman wasn’t fazed.

“I’m ugly,” she said, while pretending to cry. “I’m so hurt.”

Basara explained that he wanted no part in a physical altercation.

“It was a tough situation,” he wrote on X. “Surrounded by hostile people including 2 of his buddy’s (one his brother). If I got physical there was no good ending there.”

In the video, another man was seen tapping the Eagles fan’s shoulder, but the heckling only escalated.

The Eagles have yet to publicly address the incident.

Philadelphia won 22-10 to advance to the divisional round.
