Darrisaw (concussion) didn't practice Wednesday or Thursday.
Analysis:Darrisaw suffered a concussion Sunday against Miami. He's currently in the league's five step protocol, and he'll need to be cleared by an independent neurologist before he's able to suit up for game action. Darrisaw is in real danger of missing Sunday's matchup against New Orleans, and if that happens, Ryan Van Demark will likely step in to start at left tackle.
