Panthers Go 'Round and 'Round With QB's

The Carolina Panthers' quarterback carousel continues its wild ride.

Vinny Testaverde missed today's practice, leaving David Carr the front-runner to start on Sunday at Tennessee.

The 43-year-old Testaverde aggravated a right Achilles' tendon injury in the first half of last week's loss to Indianapolis. He sat out the second half and has been receiving extensive treatment the past three days.

Carr, who missed the Panthers' win over Arizona in their previous pouting, replaced Testaverde despite still recovering from compression fractures in his lower back. Saying he was only at 80 percent, Carr threw for 103 yards, but the Panthers were outscored 21-0 in the second half of the 31-7 loss.

Carr became the number-one QB after Jake Delhomme was lost for the season in Week 3 with a right elbow injury that required ligament replacement surgery.
