Colin Kaepernick sits out national anthem

SANTA CLARA, Calif. -- The San Francisco 49ers acknowledged Friday night that quarterback Colin Kaepernick did not stand for the national anthem before Friday's game against the Green Bay Packers.

"The national anthem is and always will be a special part of the pre-game ceremony," a team statement said. "It is an opportunity to honor our country and reflect on the great liberties we are afforded as its citizens. In respecting such American principles as freedom of religion and freedom of expression, we recognize the right of an individual to choose to participate, or not, in our celebration of the national anthem."

Pro Football Talk initially reported that Kaepernick did not stand during the song. Kaepernick was not asked about his decision to sit following the 49ers' 21-10 loss to the Packers at Levi's Stadium.

Kaepernick made his preseason debut against the Packers after sitting out the first two exhibition games because of tightness in his right shoulder. He went 2-for-6 for 14 yards and added 18 yards on four carries.
