NFL protesters are kneeling themselves out of a job.

NFL ratings in Week 11 of the anthem protests have plunged 6.3% (to 14.9 million viewers) from the same time a year ago.

The 6.3% drop represents $500 million in potential lost revenue for CBS, ESPN, Fox and NBC, Outkick reported. In the past three weeks, viewership plummeted about 5.7%, which means the cratering is accelerating.

Millions of football fans have turned off their TV sets and canceled their game tickets to protest the NFL’s disrespect of the national anthem.
