Knight (concussion) practiced Wednesday in a non-contact jersey, Theo Mackie of The Arizona Republic reports.
After suffering a concussion in Week 8 at Dallas, Knight wasn't able to practice last week before the Cardinals ruled him out ahead of this past Sunday's game in Seattle. With his return to drills this week, he's made progress through the protocol for head injuries, but the presence of the non-contact jersey indicates he's a few steps away from meeting with an independent neurologist.
