Smith (concussion) is not participating in Wednesday's walk-through practice, Olivia Reiner of The Philadelphia Inquirer reports.
Since suffering a head injury in this past Sunday's win over the Saints, Smith hasn't made enough progress through the NFL's five-step concussion protocol to resume practicing in any capacity. With A.J. Brown (hamstring) also not practicing Wednesday, Philadelphia could be without its top two wideouts for this Sunday's road matchup against the Buccaneers. In order to have a chance at playing Sunday, Brown will likely need to practice in some fashion Thursday and/or Friday and then gain clearance from an independent neurologist before exiting the protocol. Jahan Dotson, Johnny Wilson and practice squad player Parris Campbell will have to lead Philadelphia's wide receiver room if both Smith and Brown are unable to go Week 4.
