Smith (concussion) isn't participating in Wednesday's practice, Nick Underhill of NewOrleans.Football reports.
Smith was forced out of last weekend's win over the 49ers after taking a big hit to the head, and he'll now need to clear the league's five-step concussion protocol before being ready for game action. Deonte Harris and Marquez Callaway will be candidates to for increased roles behind Michael Thomas and Emmanuel Sanders if Smith is unable to play Week 11 against the Falcons.
