The Panthers are sticking with rookie quarterback Jimmy Clausen. Coach John Fox said Monday that Clausen "more than likely" will start Sunday against Arizona. "I don't think our struggles either [Sunday] or up to date have been all the quarterback position, because we've fielded a few of them," Fox said. "We'll evaluate that this week. We won't announce starters, but I don't see it changing moving forward." Clausen apologized to linebacker Jon Beason for the team's offensive woes following Sunday's loss, prompting an angry response from receiver Steve Smith. "You should apologize to the people in the huddle with you," Smith said. "He has a lot to learn. He ain't at Notre Dame anymore, that's for sure." Carolina is just 1-12 this season.
