Lynch sat during the national anthem, as captured by USA TODAY Sports Images photographers Mark J. Rebilas and Matt Kartozian, before his first preseason game with the Oakland Raiders.
Why Lynch chose to sit hasn't yet been revealed, but it comes almost one year after Colin Kaepernick began a protest of the oppression of people of color by sitting and kneeling during the playing of the national anthem during the 2016 season.
Kaepernick opted out of his contract with the San Francisco 49ers after the season, but hasn't yet been signed by another team.
Lynch, who has vocally supported Kaepernick in the past, a former quarterback on the biggest rival during Lynch's time in Seattle with the Seahawks, sat down as the national anthem played on Saturday before kickoff.
EDEN PRAIRIE, Minn. - The Minnesota Vikings waived former Huskies running back Bishop Sankey with an injured designation after he tore the anterior cruciate ligament in his right knee in the exhibition opener. When Kaepernick sat last summer, it didn't take long for the protesting to become not only an National Football League topic of discussion, but a country-wide discussion that was had. He was hurt at the end of a 14-yard run at Buffalo on Thursday and left the stadium on crutches.
