No topic has caused more consternation in the NFL this year than players kneeling in protest during the national anthem.
Eight Detroit Lions took a knee before a game against the Atlanta Falcons last month after president Donald Trump made incendiary comments encouraging owners to fire players who refused to stand for the singing of the song.
The league-wide protests have quieted in recent weeks, and every Lions player stood for the anthem the last two games. But the subject remains a sore spot with some fans who say the protests are contributing to the NFL's sagging ratings.
