HOUSTON (AP) — Rookie Davis Mills will start at quarterback for the Houston Texans on Thursday night against the Carolina Panthers with Tyrod Taylor out with a hamstring injury. Coach David Culley announced the decision Tuesday and said Taylor would be inactive. Later Tuesday the Texans placed Taylor on injured reserve which means that he must miss at least three games. Culley said the Texans plan to promote Jeff Driskel from the practice squad to back up Mills against the Panthers.
