Coach John Fox provided no further injury information on Peppers, except repeating that the defensive end sprained his knee in Sunday's win over Seattle. Peppers was in and out of the game in the second half after getting hurt.
Smith sat out Tuesday's practice with an illness after catching eight passes for 72 yards against the Seahawks.
Center Justin Hartwig (ankle) and guard Geoff Hangartner (shoulder) also did not practice. Receiver Keary Colbert (knee) remained sidelined after missing Sunday's game.
The Panthers practiced Tuesday, which is a normal off day, because of the short week ahead of Saturday's game.
