It hasn't normally been broadcast, that's just fact, sorry. "The NFL's TV partners normally do not show players before the unfurling of the American flag and singing/playing of the national anthem, except before the Super Bowl and other select games. But given viewer interest around players staging demonstrations last week, ESPN, Fox Sports, NBC Sports, CBS Sports, NFL Network and DirecTV all provided live anthem coverage during Week 3." https://www.google.com/amp/www.sportingnews.com/amp/nfl/news/nfl-national-anthem-players-kneeling-tv-coverage-espn-chiefs-redskins-monday/37l0tobocd8411sz4try5244r
