Harry (concussion) wasn't spotted at practice Friday, Mike Reiss of ESPN.com reports.
With Julian Edelman (knee) out and Harry looking unlikely to suit up Sunday against the Bills, the Patriots' available wide receivers are Damiere Byrd, Jakobi Meyers and Gunner Olszewski, with Isaiah Zuber, Mason Kinsey and Kristian Wilkerson candidates to be promoted from the team's practice squad.
