After 21 seasons, Vinny Testaverde has had enough. The 44-year-old quarterback said Saturday that he'll retire after Carolina's season finale at Tampa Bay on Sunday. "I just feel like it's time," Testaverde told The Associated Press before boarding the team bus for the airport. "Obviously at 44 it does get a little bit tougher as the weeks go by. I'm glad I'm able to do it on my own terms and walk away from the game not only healthy but to experience some of the things I've been through." Testaverde was out of the league until the Panthers, desperate for quarterback help after injuries to Jake Delhomme and David Carr, signed him on Oct. 10. Four days and only three practices later, Testaverde became the oldest starting QB to win a game when he led the Panthers to a victory at Arizona.
