The Texans offensive line is making adjustments because of injuries.
Starting right guard Zach Fulton is now at center, and backup Greg Mancz missed the entire week at practice after suffering a foot injury in last week's loss to the Green Bay Packers.
Head coach Bill O'Brien remains tight-lipped about whether starters will play today.
The Texans are preparing for Saturday's preseason matchup against the Detroit Lions in NRG Stadium. Both teams lost their first pre-season games last weekend, the Lions losing to the Patriots 31 to 3.
