SANTA CLARA -- Thad Lewis, who served as the 49ers’ No. 2 passer in Sunday’s preseason loss to the Texans, tore his ACL on a third-quarter run and is out for the season.
Lewis appeared to suffer the injury on a one-yard scramble. He came off the field following the third-down play and was examined by trainers. Chip Kelly said the 49ers likely would have inserted rookie Jeff Driskel into the game around that time anyway.
Lewis was 12-21 for a team-high 97 yards in the game. He suffered the 49ers only sack and ran four times for 10 yards.
