He started three games on defense in his career. His main role with the Cardinals was as a core special-teams player. The 49ers decided they did not need Turner because of a deep group of linebackers that includes Fred Warner, De'Vondre Campbell, Dee Winters, Demetrius Flannigan-Fowles, Jalen Graham, Curtis Robinson and seventh-round draft pick Tatum Bethune. Linebacker Dre Greenlaw is expected to miss at least the first four games of the regular season as he recovers from an Achilles tear he sustained in the Super Bowl. The 49ers signed Williams as a free agent after the club learned defensive tackle Kalia Davis would be out for approximately half of the regular season due to a knee injury, which will require surgery.
