Few players were better in the preseason than Lions running back Zach Zenner.
But his regular season is now over, after a scary injury.
Via Dave Birkett of the Detroit Free Press, Lions coach Jim Caldwell said Zenner suffered multiple cracked ribs, and is hospitalized with a partially collapsed lung.
Zenner will go on season-ending injured reserve.
The undrafted rookie from South Dakota State was beginning to carve out a bit of a niche, and will now have to go through the process of doing so again next season.
