PANTHERS OFFENSE: When the Panthers released veteran Jake Delhomme last offseason, they had no quarterback ready to step in. They passed up the available free agents and went with Matt Moore and second-round pick Jimmy Clausen. Neither could get the job done. Moore threw 10 interceptions before going on injured reserve with a torn labrum in his throwing shoulder. Clausen became the starter for the second time this season at that point, and he has yet to win a game. He looks overmatched, completing 48.6 percent of his passes for one touchdown and four interceptions. He is the lowest-rated passer among all league qualifiers at 53.8. Worse yet, Clausen is suffering post-concussion symptoms after a 31-16 loss to the Bucs and is day-to-day. If he can't play, rookie Tony Pike, who's thrown 12 passes this season, will start against the Ravens. The team also has career practice-teamer Brian St. Pierre, 30, whom they signed last week, and former Appalachian State quarterback Armanti Edwards, who was drafted as a receiver, as potential options.
