The Panthers are using the weekend to get ahead on some roster moves, crossing off 12 names in advance of next Tuesday’s deadline to get rosters from 90 to 75.
Pilares injured his knee in Thursday’s game, while Campbell (shoulder) and Zordich (knee) were injured earlier in camp.
Campbell was their backup left tackle, but his rotator cuff surgery was going to keep him out this year, and exposed how thin they were up front.
Pilares was scrambling to find a roster spot even before he was injured, as the former fifth-rounder was in a crowded group of returner-receivers.
They also waived nine players: Quarterback Colby Cameron, punter Jordan Gay, cornerback Nick Hixson, kicker Morgan Lineberry, wide receiver Dale Moss, defensive end Louis Nzegwu , linebacker Ryan Rau, safety Ricardo Silva and guard Justin Wells.
