Beason was injured when 49ers running back Carlos Hyde rammed into him, sending him backward to the turf. Beason got to his feet, but was wobbly. He was able to jog off the field, but was taken to the locker room, where he was diagnosed with a concussion. He is out for the game.
The Giants, who are already down two linebackers thanks to Devon Kennard and Jonathan Casillas being inactive, replaced Beason with first-year player Uani 'Unga.
