Dortch didn't take part in Wednesday's practice due to a shoulder injury, Tyler Drake of ArizonaSports.com reports.
Dortch joined fellow wide receiver Marquise Brown as a non-participant due to a new health concern. The two wideouts will thus have two more chances this week to put themselves in positions to play Sunday at Chicago. At the moment, Michael Wilson, Rondale Moore and Zach Pascal are the healthy receivers for the Cardinals.
