Zenner (coach's decision) is inactive for Sunday's Week 2 matchup versus the Titans, Tim Twentyman of the team's official site reports.
The versatile second-year back will take a seat for the second straight week, leaving Ameer Abdullah and Theo Riddick to soak up the majority, if not all, of the running back snaps against the Titans. Zenner saw a solid dose of action in preseason, but seventh-round pick Dwyane Washington has vaulted over him for the third running back spot the first two games of the season.
