No teams have reached out to former San Francisco 49ers quarterback Colin Kaepernick since his NFL workout earlier this month, according to ESPN.

NBC Sports Boston reporter Trenni Kusnierek said the player has intentionally been kept out of the league due to his kneeling during the national anthem as a form of protest against police brutality in 2016.

"[Kaepernick] has been black-balled, and to look at it any other way is to ignore all of the obvious facts laid out right in front of you," Kusnierek said on Boston Public Radio on Tuesday.

The NFL workout was held on a Saturday, and only seven teams attended.

Kusnierek told Boston Public Radio Kaepernick was signaling he wouldn't be played by an organization that doesn't want to deal with his politics.

"To me, that was Colin Kaepernick saying, again, 'You are not going to use me as a pawn and not play me for a fool,' and he has every right to do that," she said. "I don't think that diminishes his desire to play in the NFL, but ... if you then acquiesce and do exactly what the NFL wants you to do, even though you know it's a sham and dog and pony show, then you're playing right into their hands."
