The Seahawks’ demonstration comes as a number of athletes have followed the lead of 49ers quarterback Colin Kaepernick, who refused to stand for the playing of the national anthem in protest of what he deems are offenses against African-Americans and other minorities.

Also on Sunday, Miami Dolphins running back Arian Foster, safety Michael Thomas, linebacker Jelani Jenkins and receiver Kenny Stills kneeled on the sideline in protest.

Seahawks Hall of Famer Steve Largent told KIRO Radio last week that the national anthem is time for a player to stop, reflect and acknowledge sacrifices made for our country.

“That’s a moment as a player to stop, reflect and acknowledge that there’s been a lot of sacrifices made to get us to a point in this country, even to have to the opportunity we have as players to play this game, be paid as much as we do, and everything else,” Largent told KIRO Radio’s Ron and Don. “Taking a pot shot at some cause, whatever it is, during the national anthem is inappropriate.”
