The Lions re-signed RB Zach Zenner. The 27-year-old averaged a career-best 4.8 yards per carry last year after mustering just 3.5 across his first 3 seasons. But Zenner has yet to top 88 carries in a season and won't get there in 2019 without a prolonged absence from RB Kerryon Johnson.

Lions RB Zach Zenner is inactive for today's opener against the Cardinals. He wasn't listed on the final injury report, so this looks like a healthy scratch. Zenner is behind Ameer Abdullah, Theo Riddick and Dwayne Washington the depth chart and isn't worth rostering in redraft. We're curious to see who gets the goal-line carries for Detroit.

Lions RB Zach Zenner was evaluated for a concussion during Sunday's game against the Bears. The team hasn't announced the result of those tests, but Zenner wasn't allowed to speak with the media afterward. That suggests he did indeed sustain a concussion, putting his Week 15 status in question. RB Theo Riddick missed the Bears game with a wrist injury, and his availability going forward remains unclear. RB Dwayne Washington could be in for another busy outing this coming weekend against the Giants.

Lions RB Zach Zenner is a healthy scratch for today's opener against the Colts. He's behind rookie Dwayne Washington, as well as Ameer Abdullah and Theo Riddick, on the depth chart. Only Abdullah and Riddick are worth rostering in fantasy right now.

Tim Twentyman of Lions.com confirms that RB Zach Zenner is set for a "considerable increase" in touches with RB Joique Bell out of the picture.  Zenner went undrafted last spring but was super productive at South Dakota St. and turned in an impressive Combine performance.  He averaged 5.2 yards per carry last preseason and was seeing an increased role before going down with broken ribs and a collapsed lung in Week 6.  Zenner will be worth keeping a close eye on this offseason and is shaping up as a potential sleeper in fantasy drafts.

Lions RB Zach Zenner will miss the rest of the season with multiple cracked ribs and a collapsed lung, according to the Detroit News' Josh Katzenstein.  It's a tough break for a rookie who impressed this preseason and was starting to see a bigger role.  We'll see if Joique Bell (Achilles) can return this coming week as Detroit's "big back."  The entire backfield is in flux with RB Ameer Abdullah struggling with fumbles and suffering a stinger yesteday.
