Panthers' Beason doubtful against Cowboys

Carolina Panthers middle linebacker Jon Beason is listed as doubtful for Sunday's game against the Dallas Cowboys.

Beason will likely miss his second straight game due to a knee injury. He did not practice all week for the Panthers, who are coming off a bye week.

Cornerback Chris Gamble, who is still battling a shoulder injury, will sit out for a second straight contest as well. He practiced in full on Wednesday but suffered a setback during the session.
