Allen Park — Lions running back Zach Zenner is in a local hospital dealing with a partially-collapsed lung, an injury that will end his rookie season.
Zenner suffered what the team announced as a chest injury in the second quarter of Sunday's win over the Chicago Bears and did not return. Coach Jim Caldwell said Monday that Zenner suffered multiple broken ribs as well as the lung ailment.
Caldwell said he spoke with Zenner on the phone Sunday, and in addition to dealing with physical pain, Zenner is hurt that he'll miss out on more opportunities to play this season.
