SANTA CLARA, Calif. — An unidentified cheerleader for the San Francisco 49ers was photographed kneeling during the national anthem at Thursday evening's game between the 49ers and Oakland Raiders at Levi's Stadium, CBS San Francisco reports.

"I just thought it was peaceful, respectful, constitutionally-protected free speech," remarked Lenny Herrold, a fan in the stands whose photo of the cheerleader was one of several that went viral on social media.

The cheerleader's move comes more than two years after former 49ers quarterback Colin Kaepernick took a knee during the national anthem, which ignited a controversy that, often, has overshadowed the game of football.
