A Buffalo Bills stadium employee quit his job after at least a dozen team players kneeled during the national anthem prior to their game Sunday afternoon.

Erich Nikischer, who worked at New Era Field for almost 30 years, told WGRZ-TV that he quit right after he saw Bills players kneeling during the anthem as a form of protest.

“I waited until the national anthem ended, I took off my shirt, threw my Bills hat on the ground, walked out,” Nikischer said.

NFL PLAYERS, OWNERS REACT TO PRESIDENT DONALD TRUMP'S COMMENTS

The former employee said he believes people have the right to protest, but feels that doing so during The Star-Spangled Banner is disrespectful.

“During the National Anthem… the song that is about our country, our veterans that fight and die for us, it's just something I feel you shouldn't disrespect that way. I believe people have the right to protest; I just don't believe that's the proper venue for it,” Nikischer added.

Nikischer wrote in a now-deleted Facebook post that on Sunday he was "pushed to my limit today and had to quit. I can not work in a place where multi millionaires cry that they are oppressed."

During Sunday’s game versus the Denver Broncos, some players locked arms with one another, while others kneeled — a trend seen among more than 130 NFL players who were protesting President Trump’s recent comments about players kneeling during the anthem.

“Wouldn’t you love to see one of these NFL owners, when somebody disrespects our flag, you’d say, ‘Get that son of a b---- off the field right now. Out! He's fired,’” Trump said Friday at a rally in Alabama, sparking a Twitter firestorm on the issue from the president throughout the weekend.

"If NFL fans refuse to go to games until players stop disrespecting our Flag & Country, you will see change take place fast. Fire or suspend!" one of his tweets read.

Ahead of Sunday’s game, the Bills held a team meeting Saturday with players, coaches, staff and ownership to discuss the subject.

A statement released by the team said Trump’s comments “were divisive and disrespectful to the entire NFL community.”

“Our players have the freedom to express themselves in a respectful and thoughtful manner and we all agreed that our sole message is to provide and to promote an environment that is focused on love and equality,” the statement concluded.

During Sunday's national anthem, Bills running back LeSean McCoy seemingly didn't kneel or link arms with teammates, but rather continued his warm-ups.

After the game, McCoy said at a press conference that he "can't stand and support something where our leader of this country is just acting like a jerk."

Nikischer told WGRZ that he would never enter the Bills’ stadium again.

“I will never step foot in the that [sic] place again, I will never watch an NFL football game again until this ends,” Nikischer said.
