Panthers' QB Vinny Testaverde was inactive for Sunday's game against New Orleans, a day after he awoke with a stiff back. The 44-year-old Testaverde seemed to recover from a right Achilles' tendon injury that forced him to miss one game and leave at halftime of another. Testaverde had practiced for three days last week, and coach John Fox made him the starter on Wednesday. But Testaverde complained of a sore back when he reported to the stadium Saturday. The Panthers planned to have Testaverde test the back in warmups, but he was not seen on the field before the inactives were announced. Without Testaverde, the Panthers were left with David Carr and rookie Matt Moore.
