Waddle (concussion) will be a full practice participant Wednesday, Marcel Louis-Jacques of ESPN.com reports.
Louis-Jacques adds that depending on how Wednesday's session goes, Waddle could clear the NFL's five-step concussion protocol afterward. With that in mind, Waddle -- who was inactive for the Dolphins' 70-20 win over the Broncos in Week 3 -- appears to be trending in the right direction as Sunday's game against the Bills approaches.
