Pierre-Louis suffered the injury in the Texans' 16-9 loss to the Broncos on Sunday. Although he was able to limp off of the field, he ultimately was carted to the locker room from the sideline. With the move to IR, Pierre-Louis is guaranteed to miss at least the next four games, with a return Week 8 against the Titans being the first game he'll be eligible to play. In Pierre-Louis' absence, Blake Cashman
may take over the former's minimal role.
