SANTA CLARA, Calif. (AP) — San Francisco 49ers quarterback Colin Kaepernick says he has received death threats through social media and other avenues since he began his protest during the national anthem last month.

Kaepernick says he hasn't alerted team security and understood that such threats could occur once he began protesting over racial oppression and police brutality in the United States.

Kaepernick also said he plans to start a website soon showing he is donating the $1 million he has pledged to organizations supporting his cause of racial equality.
