Edwards (hamstring) is expected to participate in walkthroughs and individual drills at practice this week, Maddy Glab of the Bills' official site reports.
Edwards hasn't practiced since late July due to a hamstring injury. The veteran safety signed with Buffalo in the offseason following four years with Tampa Bay and one season with Kansas City. If he recovers in time for Week 1 of the regular season, Edwards will likely work behind projected starters Taylor Rapp and Damar Hamlin (hamstring) at safety, though Hamlin is also currently dealing with a hamstring issue and may not be ready for the season-opening contest versus Arizona.
