49ers place Brandon Aiyuk on IR, sign Evan Anderson to 53-man roster
As a corresponding move, the 49ers have signed defensive lineman Evan Anderson to the 53-man roster from the club’s practice squad. Anderson, who joined San Francisco as an undrafted free agent in the spring, has appeared in two games this season. He’s recorded four tackles, a sack, a tackle for loss, and a forced fumble.
