Zenner will be the Lions' No. 2 running back Sunday versus the Eagles, Tim Twentyman of the team's official site reports.
Zenner will be afforded an opportunity to build upon his 20 career carries with Ameer Abdullah (foot) on IR and Dwayne Washington (ankle) out of commission in Week 5. No matter, Theo Riddick will earn the start, relegating Zenner to work between the tackles.
