FILE - In this Thursday, Sept. 8, 2016, file photo, Denver Broncos inside linebacker Brandon Marshall (54) kneels on the sideline during the national anthem before an NFL football game against the Carolina Panthers in Denver. The dozen NFL players who have joined Kaepernick?'s protest of social injustices by kneeling or raising a fist during the national anthem have faced vitriolic, sometimes racist reactions on social media and at least one has lost endorsements. None are deterred by the backlash. (AP Photo/Joe Mahoney, File)
