Texans right offensive tackle Kendall Lamm is out for the remainder of the game after being evaluated under the NFL concussion protocol.
The head injury sustained by Lamm and a hand injury suffered by right guard Zach Fulton triggered replacements on the right side of the line.
The Texans inserted rookie Martinas Rankin at right tackle and Greg Mancz at right guard.
Fulton is questionable to return.
