Mack to join Texans practice squad

RB Marlon Mack is expected to join the Texans practice squad, according to ESPN's Adam Schefter. That means Mack couldn't find another team willing to sign him to the active roster. We'll see if Mack ends up getting called up in Houston, but he's obviously not a big part of the team's plans. He can be left on the waiver wire. RB Dameon Pierce will open the season as the Texans' lead runner.
