Marshall (concussion) didn't practice Wednesday.
It's no surprise Marshall hasn't cleared the necessary steps in the NFL's protocol for head injuries after taking a big hit from Vikings safety Xavier Woods this past Sunday. Marshall has had a slow start to his NFL career, despite seeing at least 50 percent of the Panthers' offensive snaps in five of six games. With Marshall and fellow wide receiver Alex Erickson diagnosed with concussions, the Panthers are left with Shi Smith at the position on the active roster behind starters DJ Moore and Robby Anderson.
