NFL player Colin Kaepernick refused to stand for the national anthem

American football player Colin Kaepernick has again refused to stand for the national anthem as he continues his protest against the plight of black people in the US.

A week after staying seated during The Star-Spangled Banner, the San Francisco 49ers quarterback kneeled during the anthem before a match on Thursday.

Kaepernick was joined by a former soldier who he met before the game.

Last week Nate Boyer, the Green Berets, or a former staff sergeant with the US Army Special Forces, wrote an open letter.

“Even though my initial reaction to your protest was one of anger, I’m trying to listen to what you’re saying and why you’re doing it,” Mr Boyer wrote in his letter.

“There are already plenty people fighting fire with fire, and it’s just not helping anyone or anything. So I’m just going to keep listening, with an open mind.”

Kaepernick invited Mr Boyer to join him at the match after the two met before on Thursday. As Kaepernick kneeled in demonstration Mr Boyer stood for the anthem.

Kaepernick said he’ll continue to sit out the national anthem until he sees developments in US race relations.

On Thursday, he pledged to donate $1m (£753,000) to community organisations.

The 28-year-old stirred controversy on Friday when he sat during the national anthem before the San

Francisco 49ers played with the Green Bay Packers in a exhibition game.
