Smith (concussion) was a limited participant at Wednesday's practice, John Hendrix of SI.com reports.

EDGE Analysis

Smith suffered a concussion in the Week 3 loss to the Panthers, but his ability to practice in limited fashion Wednesday implies that he's made at least some progress through the five-step protocol. He'll still have to upgrade to full activity and gain clearance from an independent neurologist to have a chance at playing Sunday against the Vikings. If Smith is ready to go, he could step into a prominent role while the statuses of fellow wideouts Michael Thomas (toe) and Jarvis Landry (foot) are uncertain.
