The Eagles have identified the fan who berated a female Packers supporter at Philadelphia’s playoff game over the weekend … and TMZ Sports has learned they’ve now kickstarted the punishment process for the guy.

Our sources say that just two days after the man in a green Eagles jacket was seen on video unloading on a Packer backer during Philly’s 22-10 Wild Card round win … the team has found out who he is and is currently determining how they want to handle the situation.

It seems a ban is on the table … however, we’re told, for now, the Eagles are still evaluating the situation.

The man who posted the footage of the altercation at Lincoln Financial Field, Packers’ content creator Alexander Basara, said on his X page the guy called his fiancée “an ugly dumb c***” for no reason other than her preferred team.

Basara was adamant the behavior was “unprovoked” … and he asked for internet sleuths to help find him.

According to BCT Partners, the fan works for them … and they promised to investigate the situation to see if they — like the Eagles — should take action against him.

“We sincerely apologize to everyone affected by this behavior,” the company said in a statement, “and remain committed to fostering a culture of respect for all.”
