Who started to take a knee when a player is injured?

The practice of taking a knee when a player is injured on the field became popularized in the NFL, particularly after quarterback Colin Kaepernick's protest against racial injustice in 2016. Players began kneeling during the national anthem to draw attention to social issues, and this gesture of kneeling in solidarity or respect for injured teammates followed suit. The act signifies a moment of respect and concern for the player's well-being.
