WATCH: Some fans boo during NFL “moment of silence” ceremony

Some Kansas City Chiefs fans booed during a NFL ceremony where both teams stood and linked arms.

“Please join us in a moment of silence dedicated to the ongoing fight for equality” the announcer said.

Prior to this ritual they played a rendition of “Lift Every Voice and Sing” a song considered by some as the black national anthem.

During the national anthem, the Houston Texans chose to stay in the locker room, while the Chiefs stood with the exception of defensive end Alex Okafor who dropped to a knee a held out his fist.
