The NFL kneeling protests have had far reaching effects beyond the game of football.

It was a month ago that Papa John’s blamed sluggish pizza sales on the league’s protests, and now a chicken wing company is joining in.

Sanderson Farms CEO Joe F. Sanderson Jr. said on a conference call on Thursday that the dipping price of chicken wings has been driven by the protests, Bloomberg reported.

“It’s just been reported to us that some of our customers think that their traffic is down because of the demonstrations by some of the NFL players,” he said in an interview after the call.

According to the report, wings were doing fantastic for the majority of 2017 but in the past three months, as protests have worn on the American fans, wing prices have steadily declined.

Prices are now 14 percent lower than they were a year ago, according to Bloomberg. Shares in Sanderson have fallen 14 percent to $145.85 on Thursday, the worst the company has seen since 2004.

On the same day, the NFL’s “Thursday Night Football” suffered its worst ratings of the season.

Sanderson competitors, Pilgrim’s Pride Corp. and Tyson Foods Inc., fell 8.1 percent and 2.5 percent respectively.

A chart provided by Bloomberg shows the trajectory of prices in 2017.

The chart shows a steady rise in prices from March until September, when prices went on a drastic decline.

The decline coincided with a massive protest by NFL players, coaches and team owners that followed President Donald Trump’s criticism of the league for continuing, what many believe to be, the anti-American behavior of kneeling during the national anthem.
