Zenner totaled just nine yards on seven carries Sunday against the Eagles, adding 23 yards on two catches.
With rookie Dwayne Washington (ankle) ruled out for the contest, Zenner assumed backup and "big-back" duties behind starting RB Theo Riddick. However, he was easily contained by a stout Eagles defensive front and found most of his success on check-down passes out of the backfield. Even if Washington is sidelined another week, Zenner will not be a strong fantasy option in Week 6 against the Rams.
