SAN DIEGO — Colin Kaepernick and San Francisco 49ers safety Eric Reid kneeled during the national anthem Thursday night, continuing the quarterback’s preseason protest of American racial injustice and minority oppression.

Kaepernick and Reid dropped to one knee while a naval officer sang “The Star-Spangled Banner” and dozens of military members unfurled an oversized flag at Qualcomm Stadium.

Kaepernick received scattered boos when he dropped to a knee, but the protest was otherwise unremarked by the San Diego crowd. The 49ers’ visit coincided with the annual Salute to the Military exhibition game for the Chargers, who have strong fan support in their city’s extensive armed forces community.

Kaepernick got much heavier boos when he took the field to start the game for the 49ers.

• In Oakland, Seahawks defensive back Jeremy Lane sat for the anthem.

THE NFL IS expected to pick up most of the cost to stage the 2017 draft in Philadelphia.

City officials said they don’t expect the NFL’s 82nd event to come at taxpayer expense, but instead expect to raise about $5 million of the $25 million budget, with the league paying for the staging and infrastructure.
