And former San Francisco 49ers quarterback Colin Kaepernick is suing the owners of NFL teams, charging they unlawfully colluded to keep him out of the league for taking a knee during the national anthem to protest police brutality and racial injustice. The lawsuit charges the owners secretly conspired to deprive Kaepernick of a job in violation of the NFL players’ union agreement. Kaepernick has remained unsigned since the 2016 season, even though he led the San Francisco 49ers to the Super Bowl in 2013 and is considered one of the league’s best quarterbacks.
