Zenner rushed 14 times for 58 yards Sunday against the Rams.
With both Theo Riddick and Dwayne Washington sidelined by knee injuries, Riddick took the reins of the Lions' backfield, even though the team inked ex-Raven Justin Forsett to a contract earlier in the week. However, not counting his game-high 19-yard scamper, Zenner averaged just three yards across 13 carries and wasn't featured in the passing game whatsoever. It's unclear at this point which player will spearhead Detroit's rushing attack in Week 7.
