San Francisco 49ers quarterback Colin Kaepernick's decision to kneel during the national anthem has resulted in threats being made against his life.
Speaking to reporters on Tuesday, the quarterback said he has received several death threats since he decided not to stand during the anthem.
Kaepernick said he had not told team security.
"To me, if something like that were to happen, you've proved my point and it'll be loud and clear to everyone why it happened," he said, via CSN Bay Area.
"And that would move this movement forward at a greater speed than what it is even now.
"I don't want this to happen, but that's the [reality] of what could happen."
The quarterback first took a knee during the national anthem prior to a preseason game against the Green Bay Packers, explaining his intent to bring attention to the killings of people of colour at the hands of police officers.
Undeterred by the threats, Kaepernick has continued through the first few weeks of the regular season.
He also spoke out on Tuesday about the death of Terence Crutcher, a 40-year-old black man who was shot dead by police on Friday.
Video made public on Monday showed Crutcher, a pastor, with his hands in the air before he was killed.
"They shot and killed a man and walked around like it wasn't a human being," Kaepernick said, via the Sacramento Bee.
"That's not right. And they should be in prison for that."
Kaepernick said he will donate $100,000 a month for the next 10 months to increase awareness about the issues.
He intends to create a website where the public can track the donations made.
