Detroit Lions running back Zach Zenner was injured during the first half of Sunday's divisional showdown with the Chicago Bears. He went into the locker room with a chest injury, according to Brad Biggs of the Chicago Tribune, and the Lions gave him a "questionable" designation to return.

Zenner has developed into a surprise contributor for the Lions this year. With starting running back Joique Bell out, the undrafted rookie has seen plenty of action. With Ameer Abdullah struggling to hold onto the ball last week, Zenner took over the majority of the ball-carrying duties.

If Abdullah starts fumbling again, the Lions will only have Theo Riddick left as a viable option at running back. Both Abdullah and Riddick are shifty backs with strong pass-catching abilities. Without Bell and Zenner, the Lions don't have a power back.

That's bad news for the NFL's worst rushing team.
