The Texans have had a turnstile at left tackle. Duane Brown, Chris Clark, Kendall Lamm and Jeff Allen all have played there this season for Houston.
Lamm left in the first quarter with a concussion. The Texans announced he will not return.
He becomes the fifth player to leave a game with a concussion in the past two weeks. The Texans lost four players to head injuries last week at Tennessee.
Allen replaced Lamm.
