EDGE Analysis

Thus, a 21-day window opens for Smith to prove his health with the aim to get back on the active roster, or else stay on IR for the rest of the season. The Saints could use reinforcements at wide receiver, as Marquez Callaway leads the position group with 13 catches through five games. Smith is ahead of Michael Thomas (ankle) in his recovery, so he has a good chance to be New Orleans' No. 1 WR for a spell when he's cleared to play.
